[citation needed] [dubious – discuss] The toxicity of N-isopropylbenzylamine has been studied as of 2022 and it has been found to produces toxicity via increasing nitric oxide in vitro. In this study, in vitro toxicity of N-isopropylbenzylamine and its toxicity-related targets were investigated in SN4741, SH-SY5Y or PC12 cell lines that model ...

The Buehler test is an in vivo test to screen for substances that cause human skin sensitisation (i.e. allergens). It was first proposed by Edwin Vernon Buehler in 1965 [1] and further explained in 1980. [2] It is a non-adjuvant test. In the test, guinea pigs are exposed to a high dose of the substance.
Benzylamine is used as a masked source of ammonia, since after N-alkylation, the benzyl group can be removed by hydrogenolysis: [10] C 6 H 5 CH 2 NH 2 + 2 RBr → C 6 H 5 CH 2 NR 2 + 2 HBr C 6 H 5 CH 2 NR 2 + H 2 → C 6 H 5 CH 3 + R 2 NH. Typically a base is employed in the first step to absorb the HBr (or related acid for other kinds of ...
