Description

Valeryl Chloride is a versatile and reactive acid chloride derivative of valeric acid, serving as a critical building block in organic synthesis. Its high reactivity makes it an essential reagent for introducing the valeryl moiety into target molecules, enabling the production of fine chemicals, active pharmaceutical ingredients (APIs), and agrochemical intermediates. This compound is particularly valuable for manufacturers in the pharmaceutical, fragrance, and polymer industries seeking reliable, high-purity acylating agents.

Application

• Pharmaceutical Synthesis: Key intermediate in the production of various active pharmaceutical ingredients (APIs) and prodrugs.
• Agrochemical Manufacturing: Used in the synthesis of herbicides, fungicides, and other crop protection agents.
• Fragrance and Flavor Industry: Serves as a precursor for esters used in creating specific flavor and fragrance compounds.
• Polymer Chemistry: Acts as a monomer or modifying agent in the synthesis of specialty polymers and coatings.
• Organic Synthesis: A fundamental acylating reagent for amide and ester formation in research and development laboratories.
• Dye and Pigment Production: Utilized in the synthesis of certain organic dyes and colorants.

Quality Control

Our Valeryl Chloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including assay, identity confirmation, and impurity profiling via GC, IR, and titration methods, to ensure it meets the stringent requirements of our global B2B clients. A Certificate of Analysis (COA) is provided with every shipment, guaranteeing traceability and compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat, sparks, and open flame. Due to its hygroscopic (moisture-sensitive) and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) to prevent decomposition. Recommended storage temperature is 2-8°C for extended stability.
