Chemical Structure
Description
tert-Butyl 3-(2-(4-fluorophenyl)acetyl)benzylcarbamate (CAS 1017781-73-5), molecular formula C20H22FNO3 and molecular weight 343.39 g/mol, is a CATO reference standard with documented purity and traceability.
tert-Butyl 3-(2-(4-fluorophenyl)acetyl)benzylcarbamate (C20H22FNO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures tert-Butyl 3-(2-(4-fluorophenyl)acetyl)benzylcarbamate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
