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 2,5-Dihydroxy-1,4-cyclohexanedicarboxylic Acid 1,4-Diethyl Ester (CAS 6966-80-9), a certified reference material (molecular formula C12H20O6, MW 260.28 g/mol) for analytical method development and quality control.
The molecular framework of 2,5-Dihydroxy-1,4-cyclohexanedicarboxylic Acid 1,4-Diethyl Ester (C12H20O6) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. 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).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
