Understanding the chemical properties of raw materials is fundamental to successful product development and manufacturing. 1,3-Propanediol, identified by CAS number 504-63-2, is a prime example of a chemical intermediate whose specific characteristics drive its widespread utility. Ningbo Inno Pharmchem Co., Ltd. emphasizes the importance of these properties and reliable sourcing for its clients.

Chemically, 1,3-Propanediol is a diol, meaning it contains two hydroxyl (-OH) groups. These hydroxyl groups are positioned at the terminal carbons of a three-carbon chain, making it a primary alcohol. This structure imparts several key properties: it is a colorless, viscous liquid with a mild odor, highly soluble in water and many organic solvents, and possesses a relatively high boiling point (around 214°C). These attributes make it an excellent humectant, solvent, and intermediate for various chemical reactions.

The presence of two primary hydroxyl groups allows 1,3-Propanediol to readily undergo esterification and etherification reactions. This reactivity is crucial for its use as a monomer in polymerization processes, most notably in the creation of Polytrimethylene Terephthalate (PTT). The formation of ester linkages between 1,3-Propanediol and terephthalic acid results in a polymer with unique thermal and mechanical properties.

Furthermore, its humectant nature stems from the ability of its hydroxyl groups to form hydrogen bonds with water molecules, effectively drawing and retaining moisture. This makes it a valuable ingredient in cosmetics for skin hydration and in industrial applications where moisture control is important. Its role as a solvent is attributed to its polarity, allowing it to dissolve a wide range of polar and semi-polar substances.
