Chemical Structure

Lactose-3’-sulfate CAS 159358-51-7 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 Lactose-3’-sulfate.

Lactose-3’-sulfate (CAS 159358-51-7), molecular formula C12H22O14S and molecular weight 422.36 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Lactose-3’-sulfate (C12H22O14S) 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
