Chemical Structure

2,3-Dihydroxybenzonitrile CAS 67984-81-0 chemical structure

Description

2,3-Dihydroxybenzonitrile (CAS 67984-81-0), molecular formula C7H5NO2 and molecular weight 135.12 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7H5NO2, 2,3-Dihydroxybenzonitrile contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 135.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), 2,3-Dihydroxybenzonitrile 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.
