Chemical Structure

Hydantoin Impurity 18 CAS CATO-C4X-214618 chemical structure

Description

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Hydantoin Impurity 18 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 129.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Hydantoin Impurity 18 (CAS CATO-C4X-214618) is a certified pharmaceutical impurity reference standard with the molecular formula C6H11NO2 and a molecular weight of 129.16 g/mol.

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), Hydantoin 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.
