Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 2-(Difluoromethoxy)-3-ethoxybenzaldehyde is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 216.18 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).
2-(Difluoromethoxy)-3-ethoxybenzaldehyde (CAS 879362-29-5) is a high-purity analytical reference standard with the molecular formula C10H10F2O3 and a molecular weight of 216.18 g/mol.
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.
