Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 9,9-Difluoro-3-oxabicyclo[3.3.1]nonane-7-carboxylic acid.
9,9-Difluoro-3-oxabicyclo[3.3.1]nonane-7-carboxylic acid (CAS 2361767-85-1) is a high-purity analytical reference standard with the molecular formula C9H12F2O3 and a molecular weight of 206.19 g/mol.
The molecular framework of 9,9-Difluoro-3-oxabicyclo[3.3.1]nonane-7-carboxylic acid (C9H12F2O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. 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. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 9,9-Difluoro-3-oxabicyclo[3.3.1]nonane-7-carboxylic acid 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.
