OXAZINES with a fused BENZENE ring.
Six-membered heterocycles containing an oxygen and a nitrogen.
Compounds formed by the joining of smaller, usually repeating, units linked by covalent bonds. These compounds often form large macromolecules (e.g., BIOPOLYMERS; PLASTICS).
A trinitrobenzene derivative with antispasmodic properties that is used primarily as a laboratory reagent.
Toxic, volatile, flammable liquid hydrocarbon byproduct of coal distillation. It is used as an industrial solvent in paints, varnishes, lacquer thinners, gasoline, etc. Benzene causes central nervous system damage acutely and bone marrow damage chronically and is carcinogenic. It was formerly used as parasiticide.
Acrylic acids or acrylates which are substituted in the C-2 position with a methyl group.
Chemical reaction in which monomeric components are combined to form POLYMERS (e.g., POLYMETHYLMETHACRYLATE).
1,2-Dihydro-3,6-pyridazinedione. A herbicide and plant growth regulator; also used to control suckering of tobacco. Its residue in food and tobacco is highly toxic, causing CNS disturbances and liver damage.
Product of the oxidation of ethanol and of the destructive distillation of wood. It is used locally, occasionally internally, as a counterirritant and also as a reagent. (Stedman, 26th ed)
Extensive collections, reputedly complete, of facts and data garnered from material of a specialized subject area and made available for analysis and application. The collection can be automated by various contemporary methods for retrieval. The concept should be differentiated from DATABASES, BIBLIOGRAPHIC which is restricted to collections of bibliographic references.
An organothiophosphorus cholinesterase inhibitor that is used as an insecticide.
Sequential operating programs and data which instruct the functioning of a digital computer.
The major group of transplantation antigens in the mouse.
The study of natural phenomena by observation, measurement, and experimentation.
A nucleoside consisting of the base guanine and the sugar deoxyribose.
A species in the genus PARVOVIRUS that has the ability to replicate and kill tumor cells in culture.
The degree to which individuals are inhibited or facilitated in their ability to gain entry to and to receive care and services from the health care system. Factors influencing this ability include geographic, architectural, transportational, and financial considerations, among others.
