Chemical Structure

2-(Methoxycarbonyl)pyridine-3-sulfonic acid CAS 1171822-48-2 chemical structure

Description

2-(Methoxycarbonyl)pyridine-3-sulfonic acid (CAS 1171822-48-2), molecular formula C7H7NO5S and molecular weight 217.20 g/mol, is a CATO reference standard with documented purity and traceability.

2-(Methoxycarbonyl)pyridine-3-sulfonic acid (C7H7NO5S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 2-(Methoxycarbonyl)pyridine-3-sulfonic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
