Chemical Structure
Description
As a certified reference material (CRM), 4,6-Dihydroxybenzene-1,3-dicarbonitrile 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.
4,6-Dihydroxybenzene-1,3-dicarbonitrile (CAS 75610-34-3) is a high-purity analytical reference standard with the molecular formula C8H4N2O2 and a molecular weight of 160.13 g/mol.
The molecular framework of 4,6-Dihydroxybenzene-1,3-dicarbonitrile (C8H4N2O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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).
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.
