Chemical Structure
Description
3-(Methylsulfonyl)pyridine-2-carboxylic Acid (CAS 61830-06-6) is a high-purity analytical reference standard with the molecular formula C7H7NO4S and a molecular weight of 201.20 g/mol.
The molecular framework of 3-(Methylsulfonyl)pyridine-2-carboxylic Acid (C7H7NO4S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
CATO manufactures 3-(Methylsulfonyl)pyridine-2-carboxylic Acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
