Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 29101-99-3 Difluoromethoxyacetic acid Acetic acid, difluoromethoxy- is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 126.06 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.
29101-99-3 Difluoromethoxyacetic acid Acetic acid, difluoromethoxy- (CAS 29101-99-3), molecular formula C3H4F2O3 and molecular weight 126.06 g/mol, is a CATO reference standard with documented purity and traceability.
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.
