1,2-Pentanediol, identified by CAS number 5343-92-0, is a diol with a unique chemical structure that dictates its versatile applications. As a key chemical intermediate and a valuable ingredient in various industries, understanding its fundamental properties and how it is produced is essential for formulators and manufacturers. Ningbo Inno Pharmchem Co., Ltd. is dedicated to ensuring clarity on the technical aspects of this compound.
Chemically, 1,2-Pentanediol is a five-carbon chain with two hydroxyl (-OH) groups attached to the first and second carbon atoms. This structure, C5H12O2, imparts specific physical and chemical characteristics. It typically presents as a colorless to light yellow, transparent liquid with a relatively low odor. Its molecular weight is approximately 104.15 g/mol. A significant property is its solubility; 1,2-Pentanediol is soluble in water and common organic solvents such as alcohol, ether, and ethyl acetate, which enhances its utility in various formulations.
The physical properties further define its application range. With a boiling point around 206 °C and a density of approximately 0.971 g/mL at 25 °C, it offers a stable liquid form under standard conditions. Its flash point of 104 °C indicates moderate flammability. While research suggests it has low skin irritation potential, minor eye irritation has been noted in animal tests, indicating the need for appropriate handling precautions.
The synthesis of 1,2-Pentanediol can be achieved through several routes. One common method involves the epoxidation of 1-pentene followed by hydrolysis. Another pathway utilizes formic acid and hydrogen peroxide in a controlled reaction process. These methods are optimized to yield high-purity 1,2-Pentanediol, with production capacities catering to industrial demand. For instance, methods yielding high purity (e.g., ≥99%) are crucial for cosmetic and pharmaceutical intermediate applications.
