Chemical Structure
Description
4-Chloro-2-(5-chloro-2-fluorophenyl)pteridine (CAS 1015236-21-1), molecular formula C12H5Cl2FN4 and molecular weight 295.10 g/mol, is a CATO reference standard with documented purity and traceability.
4-Chloro-2-(5-chloro-2-fluorophenyl)pteridine (C12H5Cl2FN4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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 4-Chloro-2-(5-chloro-2-fluorophenyl)pteridine 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.
