Chemical Structure
Description
The occurrence of Prop-2-yn-1-yl 3-chloro-5-ethoxy-4-((4-methylbenzyl)oxy)benzoate is closely related to a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Prop-2-yn-1-yl 3-chloro-5-ethoxy-4-((4-methylbenzyl)oxy)benzoate (CAS 1706442-84-3), a certified reference material (molecular formula C20H19ClO4, MW 358.82 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution, Prop-2-yn-1-yl 3-chloro-5-ethoxy-4-((4-methylbenzyl)oxy)benzoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 358.82 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
