Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Prop-2-yn-1-yl 4-((2-chlorobenzyl)oxy)-3-ethoxybenzoate (CAS 1706453-53-3), molecular formula C19H17ClO4 and molecular weight 344.79 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Prop-2-yn-1-yl 4-((2-chlorobenzyl)oxy)-3-ethoxybenzoate (C19H17ClO4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), Prop-2-yn-1-yl 4-((2-chlorobenzyl)oxy)-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.
