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 Acetate Trihydrate (CAS 6131-90-4), molecular formula C2H3O2NaH2O and molecular weight 100.05 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Sodium Acetate Trihydrate (C2H3O2NaH2O) is characterized by a carboxylic acid group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
CATO manufactures Sodium Acetate Trihydrate 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.
