We report here the synthesis of a series of N-aryl-2,3-dihydrobenzo[1,4]dioxine-6-sulfonamide and its N-substituted derivatives with benzyl chloride
and ethyl iodide.
Summary: Two novel 1,3,4-thiadiazole compounds, C15H10N4S2 (5a) and C18H19N3S2 (5b) were designed and synthesized by reactions of key intermediate 5-(pyridin-4-yl)-1,3,4-thiadiazole-2-thiol and two substituted benzyl chloride
(4-t-Bu and 3-CN).
chemical diversion experts, Mexico's Chemical Regulating Agency classified four chemicals as controlled precursor chemicals (nitroethane, nitromethane, benzaldehyde, and benzyl chloride
) used to manufacture methamphetamine and MDMA (ecstasy).
This observation rules out the possibility that the quaternary ammonium chloride merely acted as an in situ source of benzyl chloride
by chloride displacement of trimethylamine.
We also tested benzyl chloride
as an alkylating reagent for benzylation of A-Fmoc-protected hydrazine.
The benzyl chloride
leak occurred just before 11am at Protocol Developments Ltd, at the Merseyside Enterprise Park.
The drilling fluids contain hydrochloric acid, benzyl chloride
and many other chemicals.
is most often used in fibre treatment.

The Profit Before Tax of fourth quarter is Rs.71.20 crore, which shows an increase of 9.49% as compared with Rs.65.03 crore in the similar period of the previous year, which is mainly due to improvement in price realizations for Caustic Soda Group, Caustic Potash Group, Phosphoric Acid, Sodium Cyanide, Ploy Aluminium Chloride Group, Chlorinated Parafin Wax, Benzyl Chloride
and Benzyal Alcohol products.
The departments said that by May 28, 2013 they will finalize regulations or other control instruments for benzyl chloride
, a chemical intermediate used in the manufacture of other substances.
The main derivatives of chloro toluene are benzyl chloride
, benzyl alcohol, and benzaldehyde; these are used to manufacture agricultural pesticides, pharmaceuticals, paints, dyes, and perfumes.
