Glycerol Impurity 3 (Mixture of Diastereomers) CAS 54120-69-3 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 Glycerol Impurity 3 (Mixture of Diastereomers).

Glycerol Impurity 3 (Mixture of Diastereomers) (CAS 54120-69-3) is a certified pharmaceutical impurity reference standard with the molecular formula C6H12O4 and a molecular weight of 148.16 g/mol.

Glycerol Impurity 3 (Mixture of Diastereomers) (C6H12O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

As a certified reference material (CRM), Glycerol Impurity 3 (Mixture of Diastereomers) 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.
