Chemical Structure
Description
2-(1,1-Difluoroethyl)-4-methylpyridine (CAS 1401425-30-6) is a high-purity analytical reference standard with the molecular formula C8H9F2N and a molecular weight of 157.16 g/mol.
2-(1,1-Difluoroethyl)-4-methylpyridine (C8H9F2N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. 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).
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.
CATO manufactures 2-(1,1-Difluoroethyl)-4-methylpyridine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
