6-Hydroxy-2-phenylpyrimidine-4,5-dicarbonitrile CAS 887585-44-6

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 6-Hydroxy-2-phenylpyrimidine-4,5-dicarbonitrile is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 222.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

6-Hydroxy-2-phenylpyrimidine-4,5-dicarbonitrile (CAS 887585-44-6), molecular formula C12H6N4O and molecular weight 222.20 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), 6-Hydroxy-2-phenylpyrimidine-4,5-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.
