Chemical Structure
Description
Prop-2-yn-1-yl 4-(benzyloxy)-3-ethoxybenzoate (CAS 1706438-95-0), molecular formula C19H18O4 and molecular weight 310.34 g/mol, is a CATO reference standard with documented purity and traceability.
Prop-2-yn-1-yl 4-(benzyloxy)-3-ethoxybenzoate (C19H18O4) contains a flavonoid core, 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 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), Prop-2-yn-1-yl 4-(benzyloxy)-3-ethoxybenzoate 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.
