Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4-Fluoro-1H-indazol-6-yl)boronic acid pinacol ester.
(4-Fluoro-1H-indazol-6-yl)boronic acid pinacol ester (CAS 2121511-94-0), molecular formula C13H16BFN2O2 and molecular weight 262.09 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (4-Fluoro-1H-indazol-6-yl)boronic acid pinacol ester (C13H16BFN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.5, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 262.09 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
