Dimethyl Methylphosphonate (DMMP)
DMMP is an organophosphorus compound used as a flame retardant additive and chemical intermediate in flameproof coatings and plastics. It falls under HTS 3824.99.93.61 because it consists mainly of chemicals containing a phosphorus atom bonded to one methyl group with no other carbon atoms directly attached beyond that. This specific mixture classification applies to its use in industrial chemical preparations.
Methylphosphonic Acid Mixture
A stabilized mixture primarily of methylphosphonic acid used in chemical synthesis and as a precursor for phosphonate-based water treatment agents. Classified under HTS 3824.99.93.61 due to its main component being phosphorus bonded solely to a methyl group without additional carbon attachments. This preparation is common in industrial chemical supply chains.
n-Propylphosphonic Acid Formulation
Formulation primarily of n-propylphosphonic acid for use in corrosion inhibitors and scale control in oilfield chemicals. Classified in HTS 3824.99.93.61 due to the defining phosphorus-n-propyl bond with no additional carbons. This prep is optimized for industrial fluid applications.
Ethyl Methylphosphonite Preparation
Industrial preparation mainly consisting of ethyl methylphosphonite used in organophosphorus synthesis for agrochemicals and flame retardants. It matches HTS 3824.99.93.61 as the core chemical features phosphorus bonded to an ethyl group with no further carbon chain. This mixture form ensures stability for shipping and handling.
Isopropylphosphonic Dichloride Solution
A diluted industrial solution mainly of isopropylphosphonic dichloride used in specialty polymer and herbicide production. Falls under HTS 3824.99.93.61 for mixtures where phosphorus is bonded only to an isopropyl group without extended carbon. The solution form aids safe transport.
