Bempedoic Acid Impurity 34 CAS CATO-C4X-218934

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Bempedoic Acid Impurity 34.

CATO supplies Bempedoic Acid Impurity 34 (CAS CATO-C4X-218934), a pharmacopoeial impurity reference standard (molecular formula C27H41NO6S, MW 507.68 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Bempedoic Acid Impurity 34 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 507.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
