Chemical Structure

Sodium 3-methoxybenzenesulfinate CAS 15898-41-6 chemical structure

Description

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

CATO supplies Sodium 3-methoxybenzenesulfinate (CAS 15898-41-6), a certified reference material (molecular formula C7H7O3SNa, MW 194.18 g/mol) for analytical method development and quality control.

Structurally, Sodium 3-methoxybenzenesulfinate (C7H7O3SNa) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 194.18 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO manufactures Sodium 3-methoxybenzenesulfinate 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.
