Perospirone impurity 49 CAS CATO-C4X-245849

Description

The occurrence of Perospirone impurity 49 is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Perospirone impurity 49 (CAS CATO-C4X-245849) is a certified pharmaceutical impurity reference standard with the molecular formula C15H20N3S and a molecular weight of 274.40 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, Perospirone impurity 49 is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 274.40 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), Perospirone impurity 49 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.
