Chemical Structure
Description
CATO supplies 2,4,5,7-Tetranitro-9H-fluoren-9-one oxime (CAS 74339-82-5), a certified reference material (molecular formula C13H5N5O9, MW 375.21 g/mol) for analytical method development and quality control.
The molecular framework of 2,4,5,7-Tetranitro-9H-fluoren-9-one oxime (C13H5N5O9) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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).
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 2,4,5,7-Tetranitro-9H-fluoren-9-one oxime 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.
