Chemical Structure

D-Galactose-4-O-sulphate sodium salt CAS 125113-68-0 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including D-Galactose-4-O-sulphate sodium salt.

D-Galactose-4-O-sulphate sodium salt (CAS 125113-68-0) is a high-purity analytical reference standard with the molecular formula C6H11O9SNa and a molecular weight of 282.19 g/mol.

The molecular framework of D-Galactose-4-O-sulphate sodium salt (C6H11O9SNa) is characterized by a carbohydrate-derived structure, a sulfone group. 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.

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.

As a certified reference material (CRM), D-Galactose-4-O-sulphate sodium salt meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
