4-(HYDROXYMERCURY)BENZOIC ACID SODIUM SALT Chemical Properties,Uses,Production
Chemical Properties
White crystalline powder
Uses
4-(Hydroxymercuri)benzoic acid is an organic mercurial compound th at reacts via mercury-sulfur affinity with sulfhydryl groups in peptides, proteins and other molecules. PCMB may be used for the determination of sulfhydryl groups in proteins according to Boyer, by atomic absorption, and stopped-flow measurements, G. Castronuovo-Lepore et al.. It may be used for specific applications such as probing the active site of an enzyme such as cytochrome C oxidase. 4-(Hydroxymercuri)benzoic acid appeared mistakenly as p-chloromercuriobenzoate [PCMB] in earlier literature.
Safety Profile
Poison by intraperitoneal route. Mutation data reported. When heated to decomposition it emits toxic fumes of Hg and NazO. See also MERCURY COMPOUNDS.
