Products classified under HTS 2812.17.00.00
Stabilized Thionyl Chloride for Pharmaceutical Use
This stabilized form of thionyl chloride contains additives to prevent decomposition, ideal for converting alcohols and acids to chlorides in drug manufacturing. It is a chemically defined halide oxide under HTS 2812.17.00.00, meeting Chapter 28 Note 1 criteria for nonmetal compounds. Purity exceeds 99.5% with minimal impurities.
Thionyl Chloride with Pyridine Stabilizer
Thionyl chloride stabilized with 0.1% pyridine inhibits decomposition for safer storage and transport in pharma synthesis. Still classified under HTS 2812.17.00.00 as the principal compound is chemically defined thionyl chloride per Chapter notes. The stabilizer is below threshold for reclassification.
Redistilled Thionyl Chloride 99.8%
Redistilled thionyl chloride achieves 99.8% purity through multiple vacuum distillations for sensitive fine chemical synthesis. Explicitly thionyl chloride under HTS 2812.17.00.00, a nonmetal chloride oxide not covered by Chapter 29 organics. Boiling point 74-76°C.
Thionyl Chloride (SOCl2) 99% Purity
Thionyl chloride is a colorless to pale yellow liquid chemical compound with the formula SOCl2, used primarily as a chlorinating and dehydrating agent in organic synthesis. It falls under HTS 2812.17.00.00 as a chloride oxide of nonmetals, specifically thionyl chloride, distinct from metal salts or organic compounds. This high-purity grade is suitable for pharmaceutical intermediate production.
Industrial Grade Thionyl Chloride
Industrial thionyl chloride (SOCl2) is a reactive chloride oxide used in large-scale production of acid chlorides from carboxylic acids. Classified under HTS 2812.17.00.00 as a halide oxide of nonmetals per Chapter 28 notes, excluding organo-inorganic compounds. It produces sulfur dioxide and HCl gases upon reaction, requiring specialized handling.
Thionyl Chloride Anhydrous 99.9% ACS Reagent
ACS reagent-grade thionyl chloride is ultra-pure anhydrous SOCl2 for analytical and research applications, free of water to avoid hydrolysis. It qualifies under HTS 2812.17.00.00 as a pure chloride oxide of nonmetals, per subchapter II definitions. Commonly used in converting carboxylic acids to acid chlorides.
Bulk Thionyl Chloride for Agrochemical Production
Bulk thionyl chloride is supplied in tankers or IBCs for manufacturing pesticides and herbicides via chlorination reactions. Classified precisely as thionyl chloride under HTS 2812.17.00.00, a halide oxide of sulfur and oxygen (nonmetals). It reacts vigorously with water, necessitating dry storage.
Distilled Thionyl Chloride 99.5% Technical Grade
Distilled technical-grade thionyl chloride (99.5% SOCl2) is purified by fractionation for use in polymer and dye synthesis. It is a chemically defined compound under HTS 2812.17.00.00, specifically named in the tariff as a chloride oxide of nonmetals. Low iron content prevents side reactions in dyes.
High-Purity Thionyl Chloride for Electronics
Ultra-high purity thionyl chloride (99.999%) for etching and doping in semiconductor manufacturing. It qualifies as a chemically defined halide oxide under HTS 2812.17.00.00, with electronic-grade specs excluding doped forms per Chapter notes. Trace metal analysis <1ppb.
Thionyl Chloride in Glass Ampoules
Thionyl chloride packaged in 100ml glass ampoules for laboratory single-use in organic chemistry reactions. Remains under HTS 2812.17.00.00 as the compound is chemically defined, not a retail preparation per exclusions. Ampoules prevent moisture exposure.
