Labetalol Impurity 42 CAS CATO-C4X-246642

Description

Compared with other compounds in its class, the molecular weight of 336.96 g/mol gives Labetalol Impurity 42 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Labetalol Impurity 42 (CAS CATO-C4X-246642), a pharmacopoeial impurity reference standard (molecular formula C9H7Br2NO3, MW 336.96 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C9H7Br2NO3, Labetalol Impurity 42 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 336.96 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

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.

As a certified reference material (CRM), Labetalol Impurity 42 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.
