Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,2-Difluoro-cyclopropaneboronic acid pinacol ester (CAS 2411405-92-8), molecular formula C9H15BF2O2 and molecular weight 204.02 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, 2,2-Difluoro-cyclopropaneboronic acid pinacol ester is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 204.02 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.
As a certified reference material (CRM), 2,2-Difluoro-cyclopropaneboronic acid pinacol ester 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.
