Neopentyl Glycol (NPG), chemically known as 2,2-Dimethyl-1,3-propanediol and bearing the CAS number 126-30-7, is a diol that has garnered significant attention in the chemical industry for its unique properties and versatile applications. As a premier manufacturer and supplier of chemical intermediates in China, we are dedicated to providing our clients with comprehensive information about the materials they procure. Understanding the specific properties of NPG is fundamental for R&D scientists and procurement managers to optimize its use in formulations.

Physically, NPG typically presents as a white crystalline solid. Its molecular formula, C5H12O2, and molar mass of approximately 104.15 g/mol contribute to its distinct characteristics. A key property for formulators is its melting point, which is around 129°C. This solid state at ambient temperatures makes it suitable for handling in flake or pelletized forms, though it can also be supplied as a molten liquid or an aqueous solution (like the 90% NPG commonly available) for specific industrial processes. The appearance of NPG as a white crystalline solid ensures ease of integration into many manufacturing workflows.

Chemically, NPG's structure features two primary hydroxyl groups attached to a quaternary carbon atom. This steric hindrance around the hydroxyl groups is responsible for the enhanced thermal and hydrolytic stability observed in polymers and esters derived from NPG. When purchasing NPG, its purity is a critical factor. We supply high-purity NPG, often exceeding 99.0% minimum, which is vital for applications requiring consistent performance, such as in the production of high-quality polyester resins for coatings, lubricants, and plasticizers. Impurities can negatively affect reaction kinetics and final product characteristics, making it imperative to buy NPG from a trusted manufacturer.

NPG is also known for its good solubility in polar solvents like water and ethanol, and moderate solubility in non-polar solvents. This solubility profile aids in its application as a solvent or co-solvent in certain formulations. Its density and flash point are also important considerations for safe handling and processing. For instance, its flash point is typically above 100°C, indicating a relatively safe material to handle with standard industrial precautions.

For industries looking to procure Neopentyl Glycol, understanding these properties is the first step towards successful application. Whether you are developing advanced coatings, high-performance lubricants, or durable plasticizers, our commitment as a manufacturer is to provide you with the highest quality NPG.
