Description

5-Chlorovaleric Acid (CAS NO 1119-46-6) is a versatile bifunctional organic compound featuring both a carboxylic acid group and a reactive chloroalkyl chain. This structure makes it a valuable intermediate for synthesizing a wide range of more complex molecules through nucleophilic substitution and condensation reactions. It is primarily sought after by research and development chemists and process engineers in the pharmaceutical, agrochemical, and specialty chemical industries for constructing key molecular frameworks.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring a valeric acid or pentanoic acid backbone with a modifiable halogen handle.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators where the chlorovaleric moiety is incorporated into the final molecule.
• Polymer & Resin Modifier: Serves as a monomer or cross-linking agent in the production of specialty polyesters, polyamides, and coatings to alter physical properties.
• Organic Synthesis Reagent: Employed in research laboratories for the preparation of lactones, esters, amides, and other derivatives via reactions at the acid chloride or alkyl halide sites.
• Ligand & Chelating Agent Precursor: Useful for synthesizing complexing agents and ligands used in catalysis and metal ion sequestration.
• Fragrance & Flavor Intermediate: Acts as a starting material for the synthesis of certain aroma chemicals and flavor compounds.

Quality Control

Our 5-Chlorovaleric Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography (HPLC/GC) and spectroscopic methods, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

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). Keep away from heat, sparks, and open flame. Due to its nature as a strong acid/organic solvent, it should be stored separately from bases, oxidizing agents, and reactive metals.
