CATO supplies 4892-02-8 Benzoic acid, o-mercapto-, methyl ester Benzoic acid, 2-mercapto-, methyl ester 4-10-00-00280 (Beilstein Handbook Reference) AI3-26181 BRN 0956859 2-(Methoxycarbonyl)thiophenol Methyl o-mercaptobenzoate Methyl 2-mercaptobenzoate Methyl thiosalicylate Methyl-o-mercaptobenzoate NSC 30156 USAF MA-15 (CAS 4892-02-8), a certified reference material (molecular formula C8H14O2S, MW 174.26 g/mol) for analytical method development and quality control.

The molecular framework of 4892-02-8 Benzoic acid, o-mercapto-, methyl ester Benzoic acid, 2-mercapto-, methyl ester 4-10-00-00280 (Beilstein Handbook Reference) AI3-26181 BRN 0956859 2-(Methoxycarbonyl)thiophenol Methyl o-mercaptobenzoate Methyl 2-mercaptobenzoate Methyl thiosalicylate Methyl-o-mercaptobenzoate NSC 30156 USAF MA-15 (C8H14O2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
