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-1-benzyl-4-(4-ethylphenyl)azetidin-2-one (CAS 1291488-76-0), molecular formula C18H20N2O and molecular weight 280.36 g/mol, is a CATO reference standard with documented purity and traceability.
3-Amino-1-benzyl-4-(4-ethylphenyl)azetidin-2-one (C18H20N2O) contains a steroid core, an amide group, 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.
As a certified reference material (CRM), 3-Amino-1-benzyl-4-(4-ethylphenyl)azetidin-2-one 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.
