Description

Compared with other compounds in its class, the molecular weight of 344.79 g/mol gives Prop-2-yn-1-yl 4-(benzyloxy)-3-chloro-5-ethoxybenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Prop-2-yn-1-yl 4-(benzyloxy)-3-chloro-5-ethoxybenzoate (CAS 1706452-35-8) is a high-purity analytical reference standard with the molecular formula C19H17ClO4 and a molecular weight of 344.79 g/mol.

Prop-2-yn-1-yl 4-(benzyloxy)-3-chloro-5-ethoxybenzoate (C19H17ClO4) contains a flavonoid core, a hydroxyl group, an ether linkage, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Prop-2-yn-1-yl 4-(benzyloxy)-3-chloro-5-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.
