Description
CATO manufactures 1-[(3,3-Difluorocyclobutyl)methyl]pyrazole-4-boronic Acid Pinacol Ester under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
1-[(3,3-Difluorocyclobutyl)methyl]pyrazole-4-boronic Acid Pinacol Ester (CAS 2101934-11-4), molecular formula C14H21BF2N2O2 and molecular weight 298.14 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 1-[(3,3-Difluorocyclobutyl)methyl]pyrazole-4-boronic Acid Pinacol Ester is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 298.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
