Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 156.14 g/mol gives 2,6-Dioxocyclohexanecarboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,6-Dioxocyclohexanecarboxylic acid (CAS 64929-37-9) is a high-purity analytical reference standard with the molecular formula C7H8O4 and a molecular weight of 156.14 g/mol.
2,6-Dioxocyclohexanecarboxylic acid (C7H8O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 2,6-Dioxocyclohexanecarboxylic 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.
