Chemical Structure

Terbutaline Impurity 6 CAS 52144-90-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 403.51 g/mol gives Terbutaline Impurity 6 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Terbutaline Impurity 6 (CAS 52144-90-8), a pharmacopoeial impurity reference standard (molecular formula C26H29NO3, MW 403.51 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Terbutaline Impurity 6 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 403.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), Terbutaline 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.
