Description
Compared with other compounds in its class, the molecular weight of 279.11 g/mol gives 7-Fluoro-3,4-dihydro-2H-1,4-benzoxazine-6-boronic acid pinacol ester, 97% distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
7-Fluoro-3,4-dihydro-2H-1,4-benzoxazine-6-boronic acid pinacol ester, 97% (CAS 1256255-84-1) is a high-purity analytical reference standard with the molecular formula C14H19BFNO3 and a molecular weight of 279.11 g/mol.
The molecular framework of 7-Fluoro-3,4-dihydro-2H-1,4-benzoxazine-6-boronic acid pinacol ester, 97% (C14H19BFNO3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
CATO manufactures 7-Fluoro-3,4-dihydro-2H-1,4-benzoxazine-6-boronic acid pinacol ester, 97% 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.
