Chemical Structure
Description
The occurrence of 2-(3-methoxy-2-nitrophenyl)acetonitrile 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-(3-methoxy-2-nitrophenyl)acetonitrile (CAS 111795-89-2), molecular formula C9H8N2O3 and molecular weight 192.17 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(3-methoxy-2-nitrophenyl)acetonitrile (C9H8N2O3) 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 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
