2-Hydroxy-5-methylbenzene-1,3-dicarbonitrile CAS 73289-57-3

Description

Compared with other compounds in its class, the molecular weight of 158.16 g/mol gives 2-Hydroxy-5-methylbenzene-1,3-dicarbonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-Hydroxy-5-methylbenzene-1,3-dicarbonitrile (CAS 73289-57-3), a certified reference material (molecular formula C9H6N2O, MW 158.16 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 2-Hydroxy-5-methylbenzene-1,3-dicarbonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 158.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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), 2-Hydroxy-5-methylbenzene-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.
