Chemical Structure

Cyanocobalamin /Vitamin B12 Impurity 18 CAS 582-60-5 chemical structure

Description

Structurally, Cyanocobalamin /Vitamin B12 Impurity 18 (C9H10N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 146.19 g/mol, it falls into the low-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a process- or degradation-related impurity, Cyanocobalamin /Vitamin B12 Impurity 18 (CAS 582-60-5, C9H10N2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

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), Cyanocobalamin /Vitamin B12 Impurity 18 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.
