The aim of this study, therefore, was to perform an electrophilic reaction chemistry analysis to explain the differing respiratory sensitizing potentials of 16 chemicals containing both single and multiple functional groups. (cdc.gov)
None of the authors of these studies attempt to A number of workers have investigated the mechanistic offer a detailed mechanistic rationale based on the likely relationship between skin and respiratory sensitization for LMW electrophilic reaction chemistry ( 2, 3, 8, 9 ). (cdc.gov)

Acetaldehyde (IUPAC systematic name ethanal) is an organic chemical compound with the formula CH3CHO, sometimes abbreviated as MeCHO. (wikipedia.org)
The researchers subsequently scaled up some of the reactions they tested, making roughly 10g of this compound. (acs.org)
It was suggested that the reaction rates were influenced by the ionic nature of the compound in solution. (go.jp)
Occupational exposure to acetaldehyde may occur by inhalation and skin exposure at workplaces where this compound is produced or used. (who.int)

Patch tests can detect delayed allergic reactions, which can take several days to develop. (desejosardentes.com.br)
I once got a giant amount of IV Benadryl after a allergic reaction to an infusion of Vancomycin. (desejosardentes.com.br)
Histamine plays a central role in all allergic reactions and performs numerous regulatory tasks in our body. (dr-barbara-hendel.com)
