Chemical Structure

Glycero Impurity 26 CAS 1188-64-3 chemical structure

Description

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 process- or degradation-related impurity, Glycero Impurity 26 (CAS 1188-64-3, C3H10O9P2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Structurally, Glycero Impurity 26 (C3H10O9P2) contains a phosphate ester group, a carboxylic acid group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of -1.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 252.05 g/mol, it falls into the medium-molecular-weight range.

As a certified reference material (CRM), Glycero Impurity 26 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.
