Tosyl chloride 98-59-9 large in supply CAS NO.98-59-9

tosyl chloride toluenesulfonyl chloride is an important intermediate dyes in organic synthesis and raw materials for pesticides, there are three kinds of isomers, namely o-toluenesulfonyl chloride, m-toluenesulfonyl chloride and p-toluenesulfonyl chloride. relative molecular mass is 190.65. all three stimulate skin and mucous membranes, commonly used is adjacent toluenesulfonyl chloride and p-toluenesulfonyl chloride.
o-toluenesulfonyl chloride, also known as 2-methyl-benzenesulfonyl chloride, 2-toluene-sulfonyl chloride, is colorless oily liquid. the relative density is 1.3383. melting point is 10.2 ℃. boiling point is 154 ℃ (4.800 × 103pa), 126 ℃ (1.333 × 103pa). the refractive index is 1.5565. it is insoluble in water, soluble in ether, benzene and ethanol.
m-toluenesulfonyl chloride, also known as 3-methyl-benzenesulfonyl chloride, 3-toluenesulfonyl chloride, is colorless oily liquid. melting point is 11.7 ℃. boiling point is 146 ℃ (2.933 × 103pa). it is insoluble in water, soluble in alcohol, ether and benzene.
p-toluenesulfonyl chloride is also known as 4-methyl-benzenesulfonyl chloride, 4-toluenesulfonyl chloride. precipitation from ether or petroleum ether is triclinic white flaky crystal. the relative density is 1.26. melting point is 11. 7 ℃. boiling point is 164 ℃ (4.4 × 103pa), 151.6 ℃ (2.666 × 103pa), 145~146 ℃ (2.000 × 103pa), 134.5 ℃ (1.333 × 103pa). it is insoluble in water, soluble in alcohol, benzene and ether.
toluenesulfonyl chloride is called "tscl", with strong nucleophilicity and substitution reaction with nucleophilic reagent. for example, reaction with the alcohol into the ester:
roh + tscl-py → rots + py + hcl-, reaction with amine and hydrazine respectively to generate the sulfonamide and sulfonyl hydrazide:

the above information were edited and collated by xiaonan of chemicalbook.
chemical properties white flaky crystal. melting point is 71 ℃. boiling point is 151.6 ℃ (1.67kpa), 145-146 ℃ (2.0kpa). soluble in alcohol, ether and benzene, insoluble in water.
usage 1. the goods is an intermediate for disperse dyes, azoic dyes, acid dyes. also used in the production of drugs homosulfanilamide.
2. used for the analysis reagents, but also for organic synthesis, dye preparation and molecule rearrangement in the hormone synthesis.
3. used for organic synthesis, sulfa drugs and as pesticide intermediates.
production method toluene chlorosulfonation production into o-toluenesulfonyl chloride, at the same time p-toluenesulfonyl chloride is also generated. the filter cake was separated from the o-toluenesulfonyl chloride, refined to obtain p-toluenesulfonyl chloride.
chemical properties white to yellow solid
uses it can be used for organic synthesis, for example: dyes, saccharin,etc.
general description a white to gray powdered solid with a distinctive odor. insoluble in water and denser than water. contact may irritate skin, eyes and mucous membranes. may be toxic by ingestion, inhalation and skin absorption. used to make other chemicals.
air & water reactions insoluble in water.
health hazard toxic; inhalation, ingestion or skin contact with material may cause severe injury or death. contact with molten substance may cause severe burns to skin and eyes. avoid any skin contact. effects of contact or inhalation may be delayed. fire may produce irritating, corrosive and/or toxic gases. runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
fire hazard non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). contact with metals may evolve flammable hydrogen gas. containers may explode when heated.
