Description

3-Pentenoic Acid is a versatile, short-chain unsaturated carboxylic acid with significant utility as a chemical building block. Its terminal alkene and carboxylic acid functionalities make it a valuable intermediate for synthesizing a wide range of fine chemicals, pharmaceuticals, and polymers. This compound is particularly sought after by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty chemical industries for creating novel compounds and materials.

Application

• Pharmaceutical Intermediate: A key synthon in the production of active pharmaceutical ingredients (APIs), especially for molecules requiring a C5 acid moiety with an unsaturated handle for further functionalization.
• Agrochemical Synthesis: Used in the manufacture of herbicides, fungicides, and plant growth regulators, where its structure can be incorporated into more complex bioactive molecules.
• Polymer & Resin Modifier: Serves as a monomer or co-monomer in the production of specialty polymers, coatings, and adhesives, imparting flexibility and cross-linking sites.
• Flavor & Fragrance Ingredient: Acts as a precursor in the synthesis of esters and lactones used to create specific fruity or creamy flavor and aroma profiles.
• Organic Synthesis Reagent: Employed in various name reactions, including Michael additions and cyclizations, to construct heterocycles and complex organic frameworks in research laboratories.
• Lubricant & Fuel Additive Precursor: Used to synthesize derivatives that improve the performance characteristics of industrial lubricants and fuel formulations.

Quality Control

Our 3-Pentenoic Acid is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including chromatography (HPLC/GC) and spectroscopy (IR, NMR), to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment, ensuring full traceability and compliance with your internal quality standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials such as strong oxidizing agents, bases, and reducing agents. Recommended storage temperature is 2-8°C for long-term stability, although the product is stable at controlled room temperature for shorter periods. The container must be kept tightly sealed to minimize moisture absorption and oxidation.
