Description

Propionyl Chloride is a versatile and highly reactive organic acid chloride essential for introducing the propionyl group into target molecules. Its primary value lies in its role as a key acylating agent and building block in the synthesis of a wide range of fine chemicals and active pharmaceutical ingredients (APIs). This compound is critically needed by manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries for producing intermediates, dyes, and fragrances.

Application

• Pharmaceutical Intermediates: A key building block for synthesizing active pharmaceutical ingredients (APIs) and prodrugs.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and other crop protection agents.
• Dye and Pigment Manufacturing: Serves as an intermediate in the synthesis of various organic dyes and colorants.
• Perfumery and Fragrance: Employed in the creation of specific ester compounds used in flavors and fragrances.
• Polymer Chemistry: Acts as a modifying agent or monomer in the production of specialty polymers and resins.
• Organic Synthesis Reagent: A fundamental reagent for acylation reactions in research and development laboratories.

Quality Control

Our Propionyl Chloride is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including assay and impurity profiling by GC and/or HPLC. A Certificate of Analysis (COA) detailing all specifications and test results is provided with every shipment to guarantee compliance with your requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its nature as a strong acid/organic solvent and highly volatile compound, it should be kept separate from bases, amines, and oxidizing agents. Recommended storage temperature is 2-8°C for extended stability.
