Description
As a certified reference material (CRM), (S)-5,5-difluoro-2-methyltetrahydro-2H-pyran-2-carboxylic 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 (S)-5,5-difluoro-2-methyltetrahydro-2H-pyran-2-carboxylic acid (CAS 1447942-80-4), a certified reference material (molecular formula C7H10F2O3, MW 180.15 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, (S)-5,5-difluoro-2-methyltetrahydro-2H-pyran-2-carboxylic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 180.15 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.
