Glycerol Impurity 40 CAS 64528-53-6 chemical structure

Description

Glycerol Impurity 40 (CAS 64528-53-6) is a certified pharmaceutical impurity reference standard with the molecular formula C6H13O7P and a molecular weight of 228.14 g/mol.

Glycerol Impurity 40 (C6H13O7P) contains a carbohydrate-derived structure, a phosphate ester group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

As a certified reference material (CRM), Glycerol Impurity 40 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.
