Chemical Structure
Description
N-(2-Cyclohexyl-2-hydroxyethyl)-1-(thiophen-2-yl)cyclopentane-1-carboxamide (C18H27NO2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
N-(2-Cyclohexyl-2-hydroxyethyl)-1-(thiophen-2-yl)cyclopentane-1-carboxamide (CAS 1351631-99-6), molecular formula C18H27NO2S and molecular weight 321.48 g/mol, is a CATO reference standard with documented purity and traceability.
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), N-(2-Cyclohexyl-2-hydroxyethyl)-1-(thiophen-2-yl)cyclopentane-1-carboxamide 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.
