Chemical Structure
Description
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.
3-(4-methylbenzoyl)-4H,5H,6H,7H,8H-cyclohepta[b]thiophen-2-amine (CAS 436093-45-7), molecular formula C17H19NOS and molecular weight 285.40 g/mol, is a CATO reference standard with documented purity and traceability.
3-(4-methylbenzoyl)-4H,5H,6H,7H,8H-cyclohepta[b]thiophen-2-amine (C17H19NOS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
