Description

Benzoyl Chloride, 4-(4H-1,2,4-Triazol-4-Yl)- (9Ci) CAS NO 717871-76-6 is a specialized organic building block featuring a benzoyl chloride group linked to a 1,2,4-triazole heterocycle. This unique molecular architecture makes it a high-value intermediate for synthesizing complex molecules with targeted biological or material properties. It is primarily required by pharmaceutical R&D and agrochemical laboratories for the development of new active ingredients.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel drug candidates, particularly those targeting enzymes or receptors where the triazole moiety is critical for binding.
• Agrochemical Synthesis: Used to create advanced fungicides, herbicides, or plant growth regulators that incorporate the 1,2,4-triazole pharmacophore.
• Material Science Research: Serves as a monomer or cross-linking agent for developing specialty polymers, coatings, or ligands for metal-organic frameworks (MOFs).
• Chemical Biology Probes: Employed in the design of activity-based probes or affinity tags for studying biological processes.
• Custom Synthesis & Contract Manufacturing: A critical raw material for fine chemical manufacturers producing bespoke compounds for client R&D programs.

Quality Control

Every batch of our Benzoyl Chloride, 4-(4H-1,2,4-Triazol-4-Yl)- (9Ci) is produced and tested under a strict quality management system. We provide comprehensive analytical data to ensure the material meets the precise requirements of research and process development. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is supplied with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at controlled room temperature (typically 15-25°C). Due to the reactive benzoyl chloride group, the material is moisture-sensitive and should be handled under anhydrous conditions when possible. Keep away from strong bases and oxidizing agents.
