Compared with other compounds in its class, the molecular weight of 188.09 g/mol gives 5,6-Dihydroxycyclohex-5-ene-1,2,3,4-tetraone dihydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5,6-Dihydroxycyclohex-5-ene-1,2,3,4-tetraone dihydrate (CAS 63183-44-8), molecular formula C6H2O6H2O and molecular weight 188.09 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5,6-Dihydroxycyclohex-5-ene-1,2,3,4-tetraone dihydrate (C6H2O6H2O) is characterized by a carbohydrate-derived structure. 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 5,6-Dihydroxycyclohex-5-ene-1,2,3,4-tetraone dihydrate 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.
