Chemical Structure

Sodium Alginate CAS 9005-38-3 chemical structure

Description

CATO manufactures Sodium Alginate 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.

Sodium Alginate (CAS 9005-38-3), molecular formula C12H17NOC4H6O6 and molecular weight 341.36 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Sodium Alginate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 341.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
