Documented Uses

• Used as intermediate for pharmaceuticals, dyes, insecticides, and benzyl ammonium quaternary algicides; [HSDB]
• Intermediate for organic chemicals, pharmaceuticals, & dyes; intermediate for insecticide
• Intermediate in the manufacture of benzyl ammonium quarternary algicides used in swimming pool formulations.
• 2,4- and 3,4-dichlorobenzyl chloride are manufactured by side-chain chlorination of the appropriate chlorotoluene. 3,4-Dichlorobenzyl chloride containing some 2,3-dichlorobenzyl chloride is produced by the chloromethylation of o-dichlorobenzene in oleum solution.
• Final product assays approx 95% dichlorobenzyl chloride with the remaining 5% a mixture of various higher boiling chlorination by-products.
• Stauffer produces less than 300,000 lb annually.
