Description

Cinnamoyl Chloride is a versatile and highly reactive aromatic acid chloride derivative. This compound serves as a critical building block in organic synthesis, enabling the efficient introduction of the cinnamoyl moiety into target molecules. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and fine chemical industries who require a reliable and high-purity intermediate for the production of active ingredients, fragrances, and advanced materials.

Application

• Pharmaceutical Intermediate: Key reagent in the synthesis of various drug candidates and active pharmaceutical ingredients (APIs), particularly those requiring the cinnamamide or cinnamate pharmacophore.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators where the cinnamic acid derivative structure imparts biological activity.
• Perfumery and Fragrance Industry: Acts as a precursor for synthesizing esters and amides that contribute to complex, long-lasting scent profiles in perfumes and cosmetic products.
• Polymer and Material Science: Employed as a monomer or cross-linking agent in the creation of specialty polymers, coatings, and photosensitive resins.
• Organic Synthesis & Research: A fundamental reagent for Friedel-Crafts acylation, amide coupling, and esterification reactions in academic and industrial R&D laboratories.
• UV Absorber and Stabilizer Production: Serves as a starting material for manufacturing compounds used to protect plastics, paints, and coatings from photodegradation.

Quality Control

Our Cinnamoyl Chloride is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure it meets high-purity standards suitable for sensitive synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee traceability and compliance with your specifications.

Storage

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