Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3'-Hydroxy-3-oxo-6'-[[(trifluoromethyl)sulfonyl]oxy]spiro[isobenzofuran-1(3H),9'-[9H]xanthene]-6-carboxylic acid.
CATO supplies 3'-Hydroxy-3-oxo-6'-[[(trifluoromethyl)sulfonyl]oxy]spiro[isobenzofuran-1(3H),9'-[9H]xanthene]-6-carboxylic acid (CAS 1268491-68-4), a certified reference material (molecular formula C22H11F3O9S, MW 508.38 g/mol) for analytical method development and quality control.
The molecular framework of 3'-Hydroxy-3-oxo-6'-[[(trifluoromethyl)sulfonyl]oxy]spiro[isobenzofuran-1(3H),9'-[9H]xanthene]-6-carboxylic acid (C22H11F3O9S) is characterized by a flavonoid core, a sulfone 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 3'-Hydroxy-3-oxo-6'-[[(trifluoromethyl)sulfonyl]oxy]spiro[isobenzofuran-1(3H),9'-[9H]xanthene]-6-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.
