1,2-Pentanediol CAS:5343-92-0

1,2-Pentanediol CAS:5343-92-0 is an important linear diol organic chemical raw material with the chemical formula C₅H₁₂O₂. Its molecular structure features a hydroxyl group (-OH) attached to both the 1st and 2nd carbon atoms. This unique dihydroxyl structure gives it excellent water solubility, moisturizing properties, antibacterial properties, and good compatibility, while also exhibiting low toxicity and low irritation. At room temperature, this product is a colorless, transparent liquid with almost no odor, and is easily miscible with water and many organic solvents. It is widely used in various fields, including daily chemicals, pharmaceuticals, food, and industry, and holds a significant position, especially in high-end skincare products, cosmetics, and pharmaceutical excipients. It is one of the core raw materials that combines functionality and safety.

1,2-Pentanediol has become a core raw material in the daily chemical and pharmaceutical industries due to its key advantages such as "excellent moisturizing properties, broad-spectrum antibacterial properties, low toxicity, low irritation, and good compatibility." It also has wide applications in industrial and food sectors. The daily chemical industry is its most important application area, accounting for over 65% of global consumption; with the increasing consumer demand for safe and gentle daily chemical products, its application in the high-end daily chemical sector is gradually increasing.
