Chemical Structure
Description
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.
CATO supplies Prop-2-yn-1-yl 3-methoxy-4-((4-methylbenzyl)oxy)benzoate (CAS 1706463-06-0), a certified reference material (molecular formula C19H18O4, MW 310.34 g/mol) for analytical method development and quality control.
Based on its molecular formula C19H18O4, Prop-2-yn-1-yl 3-methoxy-4-((4-methylbenzyl)oxy)benzoate contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 310.34 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
