Description

Propyl 4-Chlorobutanoate is a valuable organic ester building block characterized by its chlorinated butanoate structure. This compound is essential for chemical synthesis, serving as a versatile intermediate in the production of more complex molecules for the pharmaceutical and agrochemical sectors. It is particularly sought after by R&D laboratories and industrial manufacturers requiring high-purity intermediates for active pharmaceutical ingredient (API) synthesis and specialty chemical development.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring a chlorinated butyric acid ester moiety.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators where its structure acts as a precursor.
• Organic Synthesis Reagent: Serves as an alkylating agent or ester component in various nucleophilic substitution and condensation reactions in research and development.
• Flavor and Fragrance Industry: Potential intermediate for the synthesis of certain ester-based aroma compounds, subject to purity and regulatory compliance.
• Polymer Modification: Can be used as a monomer or cross-linking agent in the synthesis of specialty polymers and coatings.
• Chemical Research: A valuable standard and reagent in academic and industrial laboratories for methodological development and scale-up studies.

Quality Control

Our Propyl 4-Chlorobutanoate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopic methods, to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing all specification results is provided with every shipment. We adhere to cGMP guidelines where applicable to support our clients in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Keep away from strong bases and incompatible materials such as strong oxidizing agents. The container should be kept tightly sealed to prevent moisture absorption and volatilization.
