Chemical Structure
Description
The occurrence of 3-(2-fluoro-3-methylphenyl)propanal is closely related to a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-(2-fluoro-3-methylphenyl)propanal (CAS 955403-65-3), a certified reference material (molecular formula C10H17FO, MW 172.24 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, fluorine substitution, 3-(2-fluoro-3-methylphenyl)propanal is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 172.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
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.
