Methyl 2,2-difluoropropanoate CAS 38650-84-9

Description

The occurrence of Methyl 2,2-difluoropropanoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Methyl 2,2-difluoropropanoate (CAS 38650-84-9), molecular formula C4H6F2O2 and molecular weight 124.09 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, Methyl 2,2-difluoropropanoate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 124.09 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.

As a certified reference material (CRM), Methyl 2,2-difluoropropanoate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
