Chemical Structure
Description
Methyl 3,3-difluorobutyrate stabilized over Potassium carbonate (CAS 1447671-66-0), molecular formula C5H8F2O2 and molecular weight 138.11 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 3,3-difluorobutyrate stabilized over Potassium carbonate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 138.11 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.
As a certified reference material (CRM), Methyl 3,3-difluorobutyrate stabilized over Potassium carbonate 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.
