2931.59.00.10 - O-Alkyl (≤ C10, including cycloalkyl) alkyl (methyl, ethyl,n- propyl or isopropyl) phosphonofluoridates

This HTS category, 2931.59.00.10, specifically classifies O-Alkyl (with an alkyl chain up to 10 carbons, including cycloalkyl) alkyl (methyl, ethyl, n-propyl, or isopropyl) phosphonofluoridates. These compounds are characterized by the presence of a phosphonofluoridate functional group, where the oxygen atom is bonded to an alkyl or cycloalkyl group, and the phosphorus atom is also bonded to an alkyl group (specifically methyl, ethyl, n-propyl, or isopropyl).

Distinguishing this category from its siblings is crucial for accurate classification. For instance, 2931.59.00.15 covers alkyl phosphonyl difluorides, which have two fluorine atoms directly bonded to the phosphorus, differing from the single fluorine in phosphonofluoridates. Other siblings, such as 2931.59.00.20 and 2931.59.00.25, classify specific methylphosphonochloridates, highlighting the presence of chlorine instead of fluorine and a different functional group arrangement. Similarly, 2931.59.00.30 and 2931.59.00.35 delve into phosphonamidic fluorides and related salts, which involve nitrogen atoms directly bonded to the phosphorus, creating a distinct chemical structure compared to the phosphonofluoridates covered here.

As this node is a leaf node, there are no further subdivisions within this specific classification. Therefore, classification to 2931.59.00.10 relies on a precise identification of the chemical structure, ensuring the presence of the O-alkyl phosphonofluoridate moiety with the specified alkyl chain lengths and types on both the oxygen and phosphorus atoms.
