4-Bromobenzaldehyde, or p-bromobenzaldehyde, is an organobromine compound with the formula BrC 6 H 4 CHO. It is one of three isomers of bromobenzaldehyde . [ 3 ] It displays reactivity characteristic of benzaldehyde and an aryl bromide .
Methyl benzoate can be isolated from the freshwater fern Salvinia molesta. [3] It is one of many compounds that is attractive to males of various species of orchid bees, which apparently gather the chemical to synthesize pheromones; it is commonly used as bait to attract and collect these bees for study.
4'-Bromo-4-methylaminorex (4B-MAR, 4'-Br-4-MAR) is a designer drug from the substituted aminorex family, first definitively identified in Austria in January 2022. Its pharmacological activity has not been reported, but it is believed to have stimulant effects.
Ethyl bromoacetate is listed by the World Health Organization as a riot control agent, and was first employed for that purpose by French police in 1912. [4] The French army used rifle grenades 'grenades lacrymogènes' [5] filled with this gas against the Germans beginning in August 1914, but the weapons were largely ineffective, even though ethyl bromoacetate is twice as toxic as chlorine.
Methyl bromoacetate is an alkylating agent. It has been used to alkylate phenol and amino groups. [4] [5] Moreover, it can be used to make vitamins and pharmaceutical drugs. It is commonly used as a reagent in chemical modification of histidine. [2] In addition, methyl bromoacetate also use in synthesize of coumarins and cis-cyclopropane.
The health effects specific to vaping these cannabis preparations is largely unknown. [187] However, cannabinoid-containing e-cigarettes are often mixed with other diluents and chemicals including vitamin E acetate, which has been associated with the onset of e-cigarette associated lung injury (EVALI).

Methyl 4-bromophenylacetate is made from 4-bromophenylacetic acid by Fischer esterification, refluxing it with methanol acidified with sulfuric acid. [3] An ethyl ester can be made in an analogous way using ethanol instead of methanol. [4] A hydrazone derivative, 2-(4-bromophenyl)acetohydrazide, is made by refluxing the methyl ester with ...
Meprobamate—marketed as Miltown by Wallace Laboratories and Equanil by Wyeth, among others—is a carbamate derivative used as an anxiolytic drug. It was the best-selling minor tranquilizer for a time, but has largely been replaced by the benzodiazepines due to their wider therapeutic index (lower risk of toxicity at therapeutically prescribed doses) and lower incidence of serious side effects.
