Chemical Structure

Disodium Citrate Sesquihydrate CAS 6132-05-4 chemical structure

Description

CATO manufactures Disodium Citrate Sesquihydrate 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.

Disodium Citrate Sesquihydrate (CAS 6132-05-4), molecular formula C6H6O7NaH2O and molecular weight 231.11 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carbohydrate-derived structure, Disodium Citrate Sesquihydrate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 231.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
