What is 2.2.4-trimethyl-1.3-pentanediol TMPD CAS 144-19-4？
2.2.4-trimethyl-1.3-pentanediol, referred to as TMPD, is one of the organic chemical intermediates of Texanol ester and TXIB plasticizer. 2.2.4-trimethyl-1.3-pentanediolis is commonly used in the synthesis of unsaturated polyester, printing ink, surfactant, plasticizer, synthetic lubricating oil, insect repellent, fragrance, polyurethane, extractant and other products. Therefore, it shows a wide range of applications and high commercial value in surface coatings and petroleum processing industries.

Storage Requirements
1. Warehouse Temperature: Cool and well-ventilated warehouse, ≤ 37℃. Store in a sealed environment at room temperature to avoid direct sunlight. Do not keep above 50℃ for a long time (close to the melting point, it will melt and form lumps).
2. The container must be sealed to prevent moisture absorption; although it has a low water solubility, it will absorb water vapor if left open for a long time.
3. Isolation Storage: Keep away from heat sources and open flames; store separately from strong oxidants and strictly do not mix.
