General description
Pyridine-3-sulfonyl chloride belongs to the class of substituted sulfonyl chlorides, which can be used as derivatization agents owing to their high proton affinity.
Application
Pyridine-3-sulfonyl chloride may be used as a derivatization agent to enhance the sensitivity of metabolites formed during the incubation of cytochrome P450 isoforms in aqueous medium, steroidal estrogens in biological samples, and bisphenols in beverages for their subsequent determination by high performance liquid chromatography coupled to tandem mass spectrometry (HPLC-MS/MS).
