Chemical Structure
Description
The occurrence of 2-Chloro-4-methyl-6-(trifluoromethyl)pyridine is closely related to a nitrile group, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Chloro-4-methyl-6-(trifluoromethyl)pyridine (CAS 749256-90-4) is a high-purity analytical reference standard with the molecular formula C7H5ClF3N and a molecular weight of 195.57 g/mol.
2-Chloro-4-methyl-6-(trifluoromethyl)pyridine (C7H5ClF3N) contains a nitrile group, fluorine/chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 2-Chloro-4-methyl-6-(trifluoromethyl)pyridine 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.
