1-(1-Ethyl-2-mercapto-1h-benzo[d]imidazol-5-yl)butan-1-one CAS 790270-89-2

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

1-(1-Ethyl-2-mercapto-1h-benzo[d]imidazol-5-yl)butan-1-one (CAS 790270-89-2), molecular formula C13H16N2OS and molecular weight 248.34 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-(1-Ethyl-2-mercapto-1h-benzo[d]imidazol-5-yl)butan-1-one (C13H16N2OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), 1-(1-Ethyl-2-mercapto-1h-benzo[d]imidazol-5-yl)butan-1-one 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.
