TY - JOUR. T1 - New uranyl open framework and sheet compounds formed via in-situ protonation of piperazine by phosphorous acid. AU - Villa, Eric. AU - Cross, Justin N.. AU - Albrecht-Schmitt, Thomas E.. PY - 2018/11/1. Y1 - 2018/11/1. N2 - Two new uranyl compounds were hydrothermally synthesized employing piperazine as an organic templating agent. The piperazine was protonated in-situ by phosphorous acid, forming the piperazinium dication featured in these compounds. The two new structures presented here are a uranyl phosphite 2D sheet and a 3D uranyl mixed phosphite-phosphate network with cation occupied channels. Both included strong hydrogen bonding from the piperazinium cation to the uranyl phosphite or mixed phosphite-phosphate network. These two structures can be reliably formed through careful control of pH of the starting solution and the reaction duration. The piperazinium uranyl phosphite compound was the latest in a family of uranyl phosphites, and demonstrates the structural ...

Phosphorus oxoacids are oxoacids of phosphorus. Phosphorus exhibits oxidation states from +1 to +5. Oxygen may be in oxidation state -2 or -1, depending on whether a compound contains the peroxide group. There are a large number of such compounds, some of which cannot be isolated and are only known through their salts. Examples of phosphorus acids include: Phosphorus oxoacids containing P in oxidation state +1: H3PO2 (or H2PO(OH)), Hypophosphorous acid or phosphinic acid, a monoprotic acid Phosphorus oxoacids containing P in oxidation state +3: H3PO3 (or HPO(OH)2), Phosphorous acid or phosphonic acid, a diprotic acid Phosphorus oxoacids containing P in oxidation state +5 (see also phosphoric acids and phosphates): H3PO4 (or PO(OH)3), Phosphoric acid, a tribasic acid A similar compound is peroxomonophosphoric acid H3PO5 (or OP(OH)2(OOH)), a tribasic acid containing a peroxide group that replaces an oxygen atom in the hydroxyl group H4P2O7 (or (OH)2(O)P-O-P(O)(OH)2), Pyrophosphoric acid, a ...

TCEP hydrochloride (Tris(2-carboxyethyl)phosphine hydrochloride) is a non-thiol reducing agent that is more stable and produces a faster S-S reductive reaction than other chemical reductants. TCEP hydrochloride is a trialkylphosphine, selectively reduces protein disuldes without altering the properties or interacting with thiol-directed agents in the reaction mixture. TCEP hydrochloride is also a commonly used reducing agent in the DNA/AuNP chemistry. - Mechanism of Action & Protocol.

Phosphonates and phosphonic acids are organophosphorus compounds containing C−PO(OH)2 or C−PO(OR)2 groups (where R = alkyl, aryl). Phosphonic acids, typically handled as salts, are generally nonvolatile solids that are poorly soluble in organic solvents, but soluble in water and common alcohols. Many commercially important compounds are phosphonates, including glyphosate, the herbicide Roundup, and ethephon, a widely used plant growth regulator. Bisphosphonates are popular drugs for treatment of osteoporosis. In biology and medicinal chemistry, phosphonate groups are used as stable bioisoteres for phosphate, such as in the antiviral nucleotide analogue, Tenofovir, one of the cornerstones of anti-HIV therapy. Phosphonates feature tetrahedral phosphorus centers. They are structurally closely related to (and often prepared from) phosphorous acid. Phosphonate salts are the result of deprotonation of phosphonic acids, which are diprotic acids: RPO(OH)2 + NaOH → H2O + RPO(OH)(ONa) (monosodium ...

The substance is inorganic, therefore biodegradation does not apply. Data from literature demonstrate the biological transformation (oxidation) of phosphite into phosphate in soil. Various microorganisms can use phosphite as phosphorous source. Nevertheless other sources related to PPP reports a DT50 soil of 157 days. The substance could be considered persistent (DT50,120) but not very persistent (DT50,180). Further tests are in course for verification. Mono- and di-potassium salts of phosphorous acid are insoluble in octanol which, therefore, suggests that it would not bioaccumulate in fish or other animals. The substance is not toxic; as a conclusion it can be stated that the substance is not PBT ...

Primary cultures of bovine adrenomedullary chromaffin cells were treated with the phosphorous acid ester, triphenyl phosphite (TPP), and the morphological changes assessed by transmission electron and scanning microscopy. Parallel studies were carried out with the cholinergic compound 0,0-diethyl-4 nitrophenyl phosphate (paraoxon) and the delayed neurotoxicant 0,0-diisopropylphosphorofluoridate (DFP). Transmission and scanning electron microscopy revealed that treatment with both of these organophosphorous compounds did not produce the ultrastructural effects that were seen with TPP. Treatment with 100 micromoles TPP for 4 or 24 hours caused a marked inhibition (90% relative to controls) of adenosine incorporation. Neither 100 micromoles paraoxon or 100 micromoles DFP had an inhibitory effect on incorporation. The results support a specific affect of the triphenylphosphite, TPP, not a general toxic effect of organophosphorous compounds since the cholinergic agent paraoxon and the delayed ...

Product form : Substance Substance name : Sodium Hypophosphite Monohydrate Chemical … The sodium hypophosphite is derived from raw materials especially yellow hypophosphite. Sodium hypophosphite has been used in the reduction of ketones in water (nine examples, 40-95 % yield). Polymer Stabilizer SHP is used as a stabilizer to prevent degradation of polymers during extrusion or in other heated processing. The Asia Pacific region, backed by the development of its electronics and automotive industry, holds high growth prospects for sodium hypophosphite manufacturers in the years to come. Polyhalogenated benzenes in the presence of a Pd/C catalyst with sodium hypophosphite in a multi- phase system consisting of a hydrocarbon solvent, concentrated aqueous alkali and a quaternary onium salt undergo reduction with rapid and progressive displacement of all their chlorine atoms. Its usage as a stabilizer and catalyst is a score to settle the sodium Hypophosphite market. References In the work the ...

Bradley et al. (1990) discussed the need for a standard reference material for ammonium determinations. Subsequently, it was decided to collect a bulk sample and prepare this first as a BGS in-house standard; later, if resources permitted, full international certification would be obtained. The material chosen needed to have a fairly high ammonium content; to be available in quantity within a reasonable distance of Keyworth; to have a similar matrix to the majority of samples currently analysed for ammonium at BGS and, ideally, to be fairly fine-grained to enable easy homogenisation with the available sample preparation equipment. These factors, coupled with the authors knowledge of possible suitable areas of the Lake District, led to the decision to collect a sample of the Skiddaw Slate Group.. ...
