Hydantoin Impurity 6 CAS 17773-41-0

Description

Compared with other compounds in its class, the molecular weight of 131.20 g/mol gives Hydantoin Impurity 6 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Hydantoin Impurity 6 (CAS 17773-41-0) is a certified pharmaceutical impurity reference standard with the molecular formula C5H9NOS and a molecular weight of 131.20 g/mol.

Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, Hydantoin Impurity 6 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 131.20 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.

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 6 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.
