Description

Isopropyl 4-(Chloroformyl)Butanoate is a versatile bifunctional chemical intermediate featuring both an ester and an acid chloride group. This molecular structure makes it a valuable building block for the synthesis of more complex molecules, particularly in pharmaceutical and fine chemical manufacturing. It is primarily sought after by research and development chemists and process engineers in the life sciences and specialty chemical sectors.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring a butanoate ester linkage.
• Peptide Mimetic Synthesis: Used in the preparation of peptide analogs and prodrugs, leveraging the reactive acid chloride for amide bond formation.
• Polymer Modification: Serves as a functional monomer or cross-linking agent for creating specialty polyesters and coatings with tailored properties.
• Liquid Crystal & OLED Material Production: Intermediate in the synthesis of advanced organic electronic materials and liquid crystal compounds.
• Agrochemical Synthesis: Employed in the research and production of novel herbicides and plant growth regulators.
• Bioconjugation Reagent: Useful in biochemical research for labeling proteins or other biomolecules via its reactive chloroformyl group.

Quality Control

Our Isopropyl 4-(Chloroformyl)Butanoate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by GC/HPLC and impurity profiling, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and specific test results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 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 and degradation. Keep away from heat, open flames, and incompatible materials such as strong bases, alcohols, and amines.
