Creatine impurity 17 CAS CATO-C4X-120917

Description

The occurrence of Creatine impurity 17 is closely related to an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Creatine impurity 17 (CAS CATO-C4X-120917) is a certified pharmaceutical impurity reference standard with the molecular formula C8H18N3O5PHCl and a molecular weight of 303.68 g/mol.

Based on its molecular formula C8H18N3O5PHCl, Creatine impurity 17 contains an amide group, a phosphate ester group, 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 303.68 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.

As a certified reference material (CRM), Creatine impurity 17 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.
