Chemical Structure
Description
Ethyl 1-cyclohexyl-2-methyl-1H-benzo[d]imidazole-5-carboxylate (CAS 1845706-43-5), molecular formula C17H22N2O2 and molecular weight 286.37 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 1-cyclohexyl-2-methyl-1H-benzo[d]imidazole-5-carboxylate (C17H22N2O2) is characterized by a steroid core, an amide group, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Ethyl 1-cyclohexyl-2-methyl-1H-benzo[d]imidazole-5-carboxylate 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.
