Chemical Structure

Benproperine Impurity 2 CAS CATO-C4X-32462 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 260.76 g/mol gives Benproperine Impurity 2 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Benproperine Impurity 2 (CAS CATO-C4X-32462), a pharmacopoeial impurity reference standard (molecular formula C16H17ClO, MW 260.76 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, Benproperine Impurity 2 is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 260.76 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.

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), Benproperine Impurity 2 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.
