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 Di-o-tolyl 9H-fluorene-2,7-disulfonate.
CATO supplies Di-o-tolyl 9H-fluorene-2,7-disulfonate (CAS 302913-97-9), a certified reference material (molecular formula C27H22O6S2, MW 506.59 g/mol) for analytical method development and quality control.
The molecular framework of Di-o-tolyl 9H-fluorene-2,7-disulfonate (C27H22O6S2) is characterized by a steroid core, a sulfone group, a hydroxyl group, an ether linkage. 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).
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 Di-o-tolyl 9H-fluorene-2,7-disulfonate 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.
