Chemical Structure

Tazobactam Impurity 6 CAS CATO-C4X-12056 chemical structure

Description

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.

CATO supplies Tazobactam Impurity 6 (CAS CATO-C4X-12056), a pharmacopoeial impurity reference standard (molecular formula C20H18O, MW 274.36 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C20H18O, Tazobactam Impurity 6 contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 274.36 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a certified reference material (CRM), Tazobactam 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.
