Chemical Structure
Description
4-(4-Chlorophenyl)-N-cycloheptyl-3-(1H-pyrrol-1-yl)thiophene-2-carboxamide (CAS 1291840-10-2), molecular formula C22H23ClN2OS and molecular weight 398.95 g/mol, is a CATO reference standard with documented purity and traceability.
4-(4-Chlorophenyl)-N-cycloheptyl-3-(1H-pyrrol-1-yl)thiophene-2-carboxamide (C22H23ClN2OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
