Description

Heptadecanoic Anhydride is a high-purity, synthetic fatty acid anhydride derived from heptadecanoic acid. This specialty chemical serves as a versatile building block and derivatization agent, offering superior reactivity for introducing the C17 acyl group into target molecules. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries seeking to modify compound properties or synthesize novel materials. Its consistent quality and reliable performance make it a critical reagent for advanced chemical synthesis and product development.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, particularly for lipid conjugation to enhance bioavailability.
• Agrochemical Synthesis: Serves as a key precursor for manufacturing specialized herbicides, fungicides, and plant growth regulators.
• Polymer Modification: Employed as a chain extender or cross-linking agent to tailor the properties of polyesters, polyamides, and other engineering plastics.
• Surface Active Agents: Acts as a raw material for producing specialized surfactants and emulsifiers with unique hydrophobic characteristics.
• Lubricant & Grease Additive: Utilized in formulating high-performance synthetic lubricants and grease thickeners to improve stability and reduce wear.
• Analytical Chemistry: Functions as a derivatization agent in gas chromatography (GC) and mass spectrometry (MS) for the analysis of alcohols, amines, and other functional groups.
• Cosmetic & Personal Care Ingredients: Used in the production of esters and other compounds for emollients and texture modifiers in high-end formulations.
• Research & Development: A valuable tool in organic synthesis laboratories for exploring new chemical entities and material science applications.

Quality Control

Our Heptadecanoic Anhydride is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is subjected to comprehensive analytical testing, including chromatography and spectroscopic methods, to verify identity, potency, and impurity profiles. Certificates of Analysis (COA) documenting all critical quality attributes are provided with every shipment. We adhere to cGMP principles where applicable, and our quality commitment supports compliance with global regulatory standards for industrial and research use.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and maintain stability. Keep away from strong bases, acids, and oxidizing agents.
