4-(Hydroxymercuri)benzoic acid is an organic mercurial compound that 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[1], 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.
