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-(5-Cyclopropyl-3-(difluoromethyl)-1H-pyrazol-1-yl)acetic acid (CAS 1002032-66-7), molecular formula C9H10F2N2O2 and molecular weight 216.18 g/mol, is a CATO reference standard with documented purity and traceability.
2-(5-Cyclopropyl-3-(difluoromethyl)-1H-pyrazol-1-yl)acetic acid (C9H10F2N2O2) contains a nitrogen-containing heterocyclic scaffold, an amide 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.
As a certified reference material (CRM), 2-(5-Cyclopropyl-3-(difluoromethyl)-1H-pyrazol-1-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.
