N-Nitroso Terbutaline impurity 132 CAS CATO-C4X-1183132

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-Nitroso Terbutaline impurity 132.

N-Nitroso Terbutaline impurity 132 (CAS CATO-C4X-1183132) is a certified pharmaceutical impurity reference standard with the molecular formula C26H28N2O4 and a molecular weight of 432.51 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, N-Nitroso Terbutaline impurity 132 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 432.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), N-Nitroso Terbutaline impurity 132 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.
