3-Hydroxybutyric Acid

3-Hydroxybutyric Acid (CAS 26063-00-3 ), commercially significant as the monomer unit of Poly(3-hydroxybutyrate) (PHB), is a bio-based building block used in the production of biodegradable thermoplastics and specialty polymers. It functions as both a polymerization precursor and a plasticizing agent in polymer systems designed for sustainable material applications. In plastics and packaging, it serves as the structural monomer for PHB-based biopolymers. This material enables the production of compostable films, rigid containers, and biodegradable packaging materials. Biotechnology manufacturers use it as a fermentation-derived intermediate for scaling microbial polyester production. Controlled monomer purity directly affects polymer molecular weight and mechanical performance. In printing and packaging substrates, it contributes to rheology modification in bio-based coating formulations, improving flow and film-forming consistency. Formulators also incorporate it into plasticizer systems to adjust the flexibility and processability of biopolymer blends. 3-Hydroxybutyric Acid is available as a liquid solution or crystalline solid, with concentration and purity specifications. Research and industrial grades are the most commonly supplied, with purity levels typically ranging from 95% to 98%+. Buyers sourcing for polymer production typically specify technical-grade material for their operations. Life sciences applications may require higher-purity specifications with documented analytical testing. The chemical is handled according to standard industrial safety protocols to ensure stability and performance in various manufacturing environments.
