Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-Fluorobenzo[c][1,2]oxaborole-1,6(3H)-diol.
7-Fluorobenzo[c][1,2]oxaborole-1,6(3H)-diol (CAS 1629141-26-9) is a high-purity analytical reference standard with the molecular formula C7H6BFO3 and a molecular weight of 167.93 g/mol.
The molecular framework of 7-Fluorobenzo[c][1,2]oxaborole-1,6(3H)-diol (C7H6BFO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 7-Fluorobenzo[c][1,2]oxaborole-1,6(3H)-diol 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.
