Chemical Structure
Description
1,4-Cyclohexanedicarboxylic Acid(Mixture of cis and trans isomers) (C8H12O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
1,4-Cyclohexanedicarboxylic Acid(Mixture of cis and trans isomers) (CAS 1076-97-7), molecular formula C8H12O4 and molecular weight 172.18 g/mol, is a CATO reference standard with documented purity and traceability.
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.
As a certified reference material (CRM), 1,4-Cyclohexanedicarboxylic Acid(Mixture of cis and trans isomers) 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.
