Description

3-Hydroxypropionic Acid (CAS NO 503-66-2) is a versatile three-carbon organic acid that serves as a key building block for a wide range of high-value chemical derivatives. Its bifunctional nature, featuring both a carboxylic acid and a hydroxyl group, makes it a crucial intermediate in the synthesis of polymers, plasticizers, and biodegradable materials. This compound is essential for manufacturers in the chemical, pharmaceutical, and bioplastics industries seeking sustainable and efficient production pathways.

Application

• Chemical Intermediate: A vital precursor for the production of acrylic acid, acrylamide, and 1,3-propanediol (PDO).
• Polymer & Bioplastics: Used in the synthesis of poly(3-hydroxypropionate) and as a monomer for creating biodegradable and biocompatible polymers.
• Pharmaceutical Synthesis: Serves as a chiral building block in the manufacture of various active pharmaceutical ingredients (APIs) and fine chemicals.
• Personal Care & Cosmetics: Employed in the formulation of moisturizers and emollients due to its humectant properties.
• Food & Feed Additives: Potential application as an acidulant or preservative, and as a precursor for feed supplements.
• Solvents & Plasticizers: Used in the production of esters that function as green solvents or plasticizers for resins.
• Adhesives & Coatings: A component in the synthesis of specialty adhesives, sealants, and coating resins.
• Industrial Fluids: Base material for manufacturing de-icing fluids, lubricants, and hydraulic fluids.

Quality Control

Our 3-Hydroxypropionic Acid is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) for every shipment, detailing key parameters such as assay, impurity profile, and physical properties. Our quality commitment aligns with cGMP principles where applicable, and we support compliance with global regulatory frameworks including REACH.

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. Keep away from incompatible materials such as strong bases, oxidizing agents, and strong acids.
