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 2,6-Dihydroxy-2,5-cyclohexadiene-1,4-dione.
CATO supplies 2,6-Dihydroxy-2,5-cyclohexadiene-1,4-dione (CAS 35069-70-6), a certified reference material (molecular formula C6H4O4, MW 140.09 g/mol) for analytical method development and quality control.
The molecular framework of 2,6-Dihydroxy-2,5-cyclohexadiene-1,4-dione (C6H4O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 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.
As a certified reference material (CRM), 2,6-Dihydroxy-2,5-cyclohexadiene-1,4-dione meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
