Description

Benzoyl Chloride, 3-Chloro-5-Formyl- (9Ci) CAS NO 153203-60-2 is a highly functionalized benzoyl chloride derivative, serving as a critical bifunctional building block in advanced organic synthesis. Its value lies in the simultaneous presence of a reactive acid chloride group and a formyl aldehyde group, both activated by a chloro substituent, enabling precise and sequential chemical modifications. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries who require a versatile intermediate for constructing complex heterocyclic scaffolds and active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel drug candidates, particularly for creating fused heterocycles and complex molecular architectures.
• Agrochemical Synthesis: Used in the development of advanced herbicides, fungicides, and insecticides, leveraging its reactive sites for structure-activity optimization.
• Ligand and Catalyst Development: Serves as a starting material for synthesizing specialized chelating ligands and organocatalysts used in asymmetric synthesis.
• Material Science Research: Employed in the creation of functionalized monomers and polymers with specific optical or electronic properties.
• Dyestuff and Pigment Intermediate: Facilitates the production of specialized chromophores and high-performance pigments.
• Custom Synthesis and Contract Manufacturing: A valuable reagent for fine chemical and custom synthesis houses serving global R&D projects.

Quality Control

Every batch of Benzoyl Chloride, 3-Chloro-5-Formyl- (9Ci) is produced and tested under a strict quality management system. We provide comprehensive analytical data to ensure the material meets the precise requirements for research and scale-up applications. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is supplied with each shipment, and custom specifications can be developed to support specific project needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and degradation. Keep away from strong bases, oxidizing agents, and sources of ignition.
