Glycerol Impurity 41 CAS 42320-97-8 chemical structure

Description

As a certified reference material (CRM), Glycerol Impurity 41 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.

Glycerol Impurity 41 (CAS 42320-97-8) is a certified pharmaceutical impurity reference standard with the molecular formula C3H7O5P and a molecular weight of 154.06 g/mol.

Based on its molecular formula C3H7O5P, Glycerol Impurity 41 contains a phosphate ester group, a carboxylic acid group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 154.06 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
