Chemical Structure

Betamethasone Impurity 83 CAS CATO-C4X-143783 chemical structure

Description

As a certified reference material (CRM), Betamethasone Impurity 83 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.

CATO supplies Betamethasone Impurity 83 (CAS CATO-C4X-143783), a pharmacopoeial impurity reference standard (molecular formula N/A, MW N/A g/mol) used for the identification and quantification of trace impurities in APIs.

Betamethasone Impurity 83 is supplied as a fully characterized reference material; its structural identity, assigned purity, and stability data are documented in the batch-specific Certificate of Analysis (COA).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
