Description
CATO manufactures 5,6-Dinitro-2,3-dihydrobenzo[b][1,4]dioxine 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.
5,6-Dinitro-2,3-dihydrobenzo[b][1,4]dioxine (CAS 59820-94-9), molecular formula C8H6N2O6 and molecular weight 226.14 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5,6-Dinitro-2,3-dihydrobenzo[b][1,4]dioxine (C8H6N2O6) is characterized by an amino-acid-derived structure, 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).
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.
