2918.29.06.00 - 1,6-Hexanediol bis(3,5-dibutyl-4-hydroxyphenyl)propionate)

This HTS classification, 2918.29.06.00, specifically covers the compound 1,6-Hexanediol bis(3,5-dibutyl-4-hydroxyphenyl)propionate. This is an ester derived from a dicarboxylic acid and a phenol-containing alcohol. Its structure features a central 1,6-hexanediol core linked to two substituted phenyl propionate groups, which themselves contain bulky butyl substituents and hydroxyl groups on the phenolic rings. The primary characteristic is its complex ester structure derived from a diol and a phenolic compound with specific alkyl substitutions.

Distinguishing this category from its siblings relies on the precise chemical structure of the compounds listed. For instance, sibling categories such as 2918.29.04.00 and 2918.29.08.00 cover simpler cresotic acids and hydroxybenzoic acids. Other siblings like 2918.29.20.00 and 2918.29.22.00 represent gentisic acid, hydroxycinnamic acid, and p-hydroxybenzoic acid, respectively. The key differentiator for 2918.29.06.00 is the presence of the 1,6-hexanediol ester linkage to a complex, heavily substituted hydroxyphenyl propionate moiety, setting it apart from the simpler phenolic acids and their derivatives found in other "Other" subheadings within this group.

As 2918.29.06.00 represents a leaf node within the HTS classification system, there are no further subcategories. Classification into this specific code is determined by the direct identification of the compound 1,6-Hexanediol bis(3,5-dibutyl-4-hydroxyphenyl)propionate based on its unique chemical name and structure, fulfilling the requirements of the parent categories for carboxylic acids with phenol functions and excluding other specifically enumerated items at this level.
