2905.39.20.00 - Neopentyl glycol

This HTS classification, 2905.39.20.00, specifically covers Neopentyl glycol. Neopentyl glycol is an organic compound classified as an acyclic diol. It is characterized by its structure containing two hydroxyl (-OH) groups and a neopentyl structure, which imparts unique properties such as excellent hydrolytic stability and resistance to UV radiation. These characteristics make it a valuable intermediate in various chemical applications.

Within the broader category of "Diols," 2905.39.20.00 is distinguished from its siblings by the specific chemical structure and applications of neopentyl glycol. For instance, butylene glycol (2905.39.10.00) and hexylene glycol (2905.39.60.00) are other acyclic diols that differ in their carbon chain length and arrangement, leading to distinct physical and chemical properties and thus different end uses in industries like cosmetics, pharmaceuticals, and solvents. This classification ensures that neopentyl glycol is accurately identified based on its unique molecular composition.

As this is a leaf node within the HTS structure, there are no further subcategories for 2905.39.20.00. The classification is specific to neopentyl glycol itself, and any further subdivisions would typically be at a more granular level of detail or in separate HTS codes for derivatives or mixtures containing neopentyl glycol. Therefore, the primary focus for classification at this level is the accurate identification of the substance as neopentyl glycol based on its chemical identity and properties.
