Chemical Structure
Description
The occurrence of Methyl 4-phenyl-4-(phenylamino)but-2-ynoate is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Methyl 4-phenyl-4-(phenylamino)but-2-ynoate (CAS 1432053-77-4), molecular formula C17H15NO2 and molecular weight 265.31 g/mol, is a CATO reference standard with documented purity and traceability.
Methyl 4-phenyl-4-(phenylamino)but-2-ynoate (C17H15NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), Methyl 4-phenyl-4-(phenylamino)but-2-ynoate 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.
