neopentyl glycol CAS#126-30-7
High Chemical and Thermal Stability: Unique molecular structure provides excellent resistance to heat and chemical degradation.
Excellent Solubility: Soluble in water and various organic solvents, ensuring flexibility in different formulations.
Efficient Reactivity: Hydroxyl groups on primary carbon atoms enable rapid esterification, improving processing efficiency.
Enhanced Structural Performance: Methyl-substituted structure contributes to improved durability and performance of derivatives.
Product Description: Neopentyl Glycol (CAS# 126-30-7)
Neopentyl glycol (NPG), with the chemical formula C₅H₁₂O₂, is a propane-1,3-diol featuring two methyl groups at the 2-position. It is soluble in water, benzene, and chloroform, and highly soluble in ethanol and diethyl ether.
NPG is a unique polyalcohol that offers excellent performance in a wide range of applications due to its high chemical and thermal stability. These properties arise from its molecular structure: the hydroxyl groups are located on primary carbon atoms, enabling rapid esterification, while the presence of two methyl groups on the alpha carbon enhances the overall stability of NPG and its derivatives.
