Chemical Structure
Description
The occurrence of 2-Methyl-6-nitrobenzonitrile is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Methyl-6-nitrobenzonitrile (CAS 1885-76-3), molecular formula C8H6N2O2 and molecular weight 162.15 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 2-Methyl-6-nitrobenzonitrile is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 162.15 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).
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-Methyl-6-nitrobenzonitrile 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.
