Chemical Structure
Description
The occurrence of 7-Methylquinoxaline-2-carbonitrile is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
7-Methylquinoxaline-2-carbonitrile (CAS 14334-17-9) is a high-purity analytical reference standard with the molecular formula C10H7N3 and a molecular weight of 169.18 g/mol.
The molecular framework of 7-Methylquinoxaline-2-carbonitrile (C10H7N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 7-Methylquinoxaline-2-carbonitrile 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.
