Chemical Structure

3,5-Dicarboxypyridine 1-oxide CAS 39911-72-3 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 3,5-Dicarboxypyridine 1-oxide (CAS 39911-72-3), a certified reference material (molecular formula C7H5NO5, MW 183.12 g/mol) for analytical method development and quality control.

Structurally, 3,5-Dicarboxypyridine 1-oxide (C7H5NO5) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 183.12 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 3,5-Dicarboxypyridine 1-oxide 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.
