Chemical Structure
Description
As a certified reference material (CRM), (S)-2-(Difluoromethoxy)propanoic acid 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.
(S)-2-(Difluoromethoxy)propanoic acid (CAS 1604374-53-9), molecular formula C4H6F2O3 and molecular weight 140.09 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, (S)-2-(Difluoromethoxy)propanoic acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 140.09 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
