2931.46.00.00 - 2,4,6-Tripropyl-1,3,5,2,4,6-trioxatriphosphinane 2,4,6-trioxide

This HTS category, 2931.46.00.00, specifically classifies 2,4,6-Tripropyl-1,3,5,2,4,6-trioxatriphosphinane 2,4,6-trioxide. This compound is a cyclic organophosphorus derivative characterized by the presence of propyl groups attached to a trioxatriphosphinane ring structure, with oxygen atoms double-bonded to the phosphorus atoms. Its unique molecular structure and the absence of halogens are key distinguishing features within the broader group of non-halogenated organophosphorous derivatives.

The specificity of this classification lies in its exact chemical name, differentiating it from other organophosphorus compounds within the 2931.4 series. For instance, while siblings like dimethyl methylphosphonate (2931.41.00.00) and diethyl ethylphosphonate (2931.42.00.00) are simpler phosphonates, and methylphosphonic acid (2931.44.00.00) and its salts (2931.45.00.00) represent related but distinct chemical entities, 2931.46.00.00 precisely identifies a cyclic trioxide with propyl substituents.

As this is a leaf node within the HTS classification, there are no further subcategories. Classification under 2931.46.00.00 is therefore determined by the definitive identification of the chemical substance as 2,4,6-Tripropyl-1,3,5,2,4,6-trioxatriphosphinane 2,4,6-trioxide, based on its chemical structure and properties, distinguishing it from other organophosphorus compounds.
