Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 3-Oxocyclobutane-1,2-dicarboxylic acid (CAS 2231673-47-3), a certified reference material (molecular formula C6H6O5, MW 158.11 g/mol) for analytical method development and quality control.
The molecular framework of 3-Oxocyclobutane-1,2-dicarboxylic acid (C6H6O5) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 3-Oxocyclobutane-1,2-dicarboxylic acid 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.
