Overview

3-(2,4-dichlorophenyl)-6-fluoro-2-(1,2,4-triazol-1-yl)quinazolin-4-one (CAS 136426-54-5) is a specialized quinazolinone derivative featuring triazole and halogenated phenyl substituents. This complex heterocyclic compound, with the molecular formula C16H8Cl2FN5O and molecular weight of 376.2 g/mol, belongs to the quinazolinone family of organic compounds. The molecule incorporates multiple functional groups including a dichlorophenyl ring, a fluorine atom, and a triazole moiety, which contribute to its unique chemical properties and biological activity profile. The presence of these electron-withdrawing substituents significantly influences the compound's reactivity and stability characteristics. From a safety perspective, this substance requires careful handling as indicated by its classification under multiple acute toxicity categories (Acute Tox. 3 and 4) and specific target organ toxicity (STOT RE 1). The compound also exhibits skin irritation properties and presents environmental concerns with its Aquatic Acute 1 classification. The GHS pictograms GHS06, GHS08, and GHS09 emphasize the need for appropriate personal protective equipment and environmental precautions. Its ADR classification as Class 6.1 indicates toxic substance transport requirements. Industrial applications typically include pharmaceutical intermediate synthesis and specialized chemical research. The compound's structural complexity makes it valuable in medicinal chemistry programs, particularly those targeting specific biological pathways. Unlike simpler aromatic compounds such as N-methylaniline, this quinazolinone derivative offers enhanced selectivity in biochemical applications due to its multiple heteroatoms and substituent pattern. OYSI maintains technical-grade stocks of this specialized compound to support European research and development programs requiring high-purity heterocyclic intermediates.
