Chemical Structure

Sodium 2-Nitrophenoxide CAS 824-39-5 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.

Sodium 2-Nitrophenoxide (CAS 824-39-5) is a high-purity analytical reference standard with the molecular formula C6H4NO3Na and a molecular weight of 161.09 g/mol.

Sodium 2-Nitrophenoxide (C6H4NO3Na) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 2-Nitrophenoxide 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.
