Description

Octanoic Acid CAS NO 124-07-2 is a medium-chain fatty acid, also known as caprylic acid, that serves as a versatile intermediate and functional ingredient across multiple industries. Its value lies in its dual functionality as a building block for chemical synthesis and as an active agent with antimicrobial and surfactant properties. This product is essential for manufacturers in the food & flavor, pharmaceutical, cosmetic, and industrial chemical sectors seeking reliable, high-purity raw materials.

Application

• Food & Flavor Industry: Used as a flavoring agent and as a precursor for the synthesis of esters that impart fruity notes (e.g., ethyl caprylate).
• Pharmaceutical & Nutraceuticals: Employed as an intermediate in drug synthesis and in the formulation of medium-chain triglyceride (MCT) oils for nutritional supplements.
• Personal Care & Cosmetics: Acts as an emulsifier, surfactant, and antimicrobial agent in soaps, creams, and deodorants.
• Industrial Chemicals: Serves as a key raw material for producing metal soaps (e.g., aluminum, cobalt octoates) used as driers in paints, inks, and PVC stabilizers.
• Agrochemicals: Utilized in the synthesis of herbicides, pesticides, and plant growth regulators.
• Plasticizers & Lubricants: Functions as an intermediate for ester-based plasticizers and synthetic lubricants.
• Antimicrobial Agent: Directly applied for its fungicidal and bactericidal properties in agricultural and preservation applications.
• Perfumery: Used in the manufacture of fragrance compounds due to its fatty, slightly rancid odor at high concentrations.

Quality Control

Our Octanoic Acid is produced and tested under a stringent quality management system to ensure batch-to-batch consistency and compliance with relevant industry standards, including FCC and USP grades where applicable. Each lot undergoes comprehensive analytical testing, including assay, identity confirmation, and impurity profiling. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong bases and oxidizing agents. Recommended storage temperature is between 15°C and 25°C. Keep container tightly sealed when not in use to minimize moisture absorption and oxidation.
