Etomidate impurity 68 CAS CATO-C4X-188468 chemical structure

Description

As a certified reference material (CRM), Etomidate impurity 68 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.

Etomidate impurity 68 (CAS CATO-C4X-188468) is a certified pharmaceutical impurity reference standard with the molecular formula C20H21N3OS and a molecular weight of 351.47 g/mol.

Based on its molecular formula C20H21N3OS, Etomidate impurity 68 contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 351.47 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
