Chemical Structure
Description
CATO supplies 3-Cyclopropoxy-4-hydroxybenzaldehyde (CAS 569685-48-9), a certified reference material (molecular formula C10H10O3, MW 178.18 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H10O3, 3-Cyclopropoxy-4-hydroxybenzaldehyde contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 178.18 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.
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.
