Description
CATO manufactures 4-Chloro-2-(2-fluorophenyl)quinazoline 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.
4-Chloro-2-(2-fluorophenyl)quinazoline (CAS 610276-37-4), molecular formula C14H8ClFN2 and molecular weight 258.68 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution, 4-Chloro-2-(2-fluorophenyl)quinazoline is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 258.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
