Description
As a certified reference material (CRM), Glycerol Impurity 36 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.
CATO supplies Glycerol Impurity 36 (CAS 14180-03-1), a pharmacopoeial impurity reference standard (molecular formula C7H15ClO3, MW 182.65 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C7H15ClO3, Glycerol Impurity 36 contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 182.65 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
