Description

Hydroxyundecanoic Acid CAS NO 6336-28-3 is a versatile medium-chain fatty acid derivative featuring a hydroxyl group, which imparts unique chemical reactivity and polarity. This bifunctional nature makes it a valuable intermediate for synthesizing specialty polymers, lubricants, and cosmetic ingredients. It is particularly sought after by manufacturers in the personal care, fine chemical, and polymer industries for its ability to modify surface properties and create novel molecular architectures.

Application

• Polymer & Resin Intermediates: As a monomer or chain extender for producing polyesters, polyamides, and other specialty polymers with tailored flexibility and hydrophilicity.
• Lubricant & Grease Additives: Used in the formulation of synthetic esters and additives that enhance lubricity, thermal stability, and corrosion resistance in industrial and automotive lubricants.
• Cosmetic & Personal Care Ingredients: Serves as a building block for emollients, surfactants, and viscosity modifiers in creams, lotions, and hair care products.
• Pharmaceutical Intermediates: Employed in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs due to its metabolically relevant fatty acid structure.
• Flavor & Fragrance Synthesis: Acts as a precursor for lactones and other aroma chemicals that contribute fruity and creamy notes.
• Metal Working Fluids: Incorporated as a corrosion inhibitor and lubricity agent in cutting and grinding fluids.
• Research & Development: Used as a standard or reagent in chemical research for studying fatty acid metabolism and organic synthesis pathways.

Quality Control

Our Hydroxyundecanoic Acid is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing, including assay (HPLC), identification (IR), and impurity profile analysis, to ensure it meets precise specifications. Certificates of Analysis (COA) documenting purity, physical properties, and conformance are available for every shipment. We adhere to cGMP principles where applicable to support our customers in regulated industries.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality.
