Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-Amino-N-(2,6-dichlorophenyl)-6,7,8,9-tetrahydro-5H-cyclohepta[b]thieno[3,2-e]pyridine-2-carboxamide (CAS 387831-20-1), molecular formula C19H17Cl2N3OS and molecular weight 406.33 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, 3-Amino-N-(2,6-dichlorophenyl)-6,7,8,9-tetrahydro-5H-cyclohepta[b]thieno[3,2-e]pyridine-2-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 406.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 3-Amino-N-(2,6-dichlorophenyl)-6,7,8,9-tetrahydro-5H-cyclohepta[b]thieno[3,2-e]pyridine-2-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.
