Chemical Structure
Description
CATO supplies Ethyl (3R,4S)-3,4-difluorocyclopentane-1-carboxylate (CAS 2448339-47-5), a certified reference material (molecular formula C8H12F2O2, MW 178.18 g/mol) for analytical method development and quality control.
Ethyl (3R,4S)-3,4-difluorocyclopentane-1-carboxylate (C8H12F2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. 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.
As a certified reference material (CRM), Ethyl (3R,4S)-3,4-difluorocyclopentane-1-carboxylate 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.
