Chemical Structure

Hydantoin Impurity 17 CAS 1460-33-9 chemical structure

Description

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.

CATO supplies Hydantoin Impurity 17 (CAS 1460-33-9), a pharmacopoeial impurity reference standard (molecular formula C6H11NO2, MW 129.16 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Hydantoin Impurity 17 (C6H11NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 129.16 g/mol, it falls into the low-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), Hydantoin 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.
