Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 159.55 g/mol gives 2-Chloro-4-fluoropyridine-3-carbaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Chloro-4-fluoropyridine-3-carbaldehyde (CAS 1060809-21-3) is a high-purity analytical reference standard with the molecular formula C6H3ClFNO and a molecular weight of 159.55 g/mol.
2-Chloro-4-fluoropyridine-3-carbaldehyde (C6H3ClFNO) contains an amide group, a hydroxyl group, an ether linkage, 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).
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-Chloro-4-fluoropyridine-3-carbaldehyde 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.
