Chemical Structure
Description
As a certified reference material (CRM), 2,2-Difluoro-2-(oxetan-3-yl)acetic 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.
CATO supplies 2,2-Difluoro-2-(oxetan-3-yl)acetic acid (CAS 1780732-24-2), a certified reference material (molecular formula C5H6F2O3, MW 152.10 g/mol) for analytical method development and quality control.
2,2-Difluoro-2-(oxetan-3-yl)acetic acid (C5H6F2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
