Chemical Structure
Description
3-((4-(Tert-butyl)benzyl)oxy)benzo[b]thiophene-2-carbonitrile (CAS 320422-43-3), molecular formula C20H19NOS and molecular weight 321.44 g/mol, is a CATO reference standard with documented purity and traceability.
3-((4-(Tert-butyl)benzyl)oxy)benzo[b]thiophene-2-carbonitrile (C20H19NOS) 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.
As a certified reference material (CRM), 3-((4-(Tert-butyl)benzyl)oxy)benzo[b]thiophene-2-carbonitrile 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.
