Dark green or brown-red powder | [Definition]
ChEBI: A member of the class of 2,1-benzoxathioles that is 2,1-benzoxathiole 1,1-dioxide in which both of the hydrogens at position 3 have been substituted by 4-hydroxy-5-methylphenyl groups. | [Uses]
Acid-base indicator. | [Purification Methods]
Crystallise it from glacial acetic acid. Dry it in air. Dissolve it in aqueous 5% NaHCO3 solution and precipitate it from a hot solution by dropwise addition of aqueous HCl. Repeat the procedure till the UVmax does not increase. [Beilstein 19 IV 1133.] |

29349990 | [Toxicity]
A potent lacrimator
which is chemically stable and retains its irritancy in water
and so can be used in liquid jets in personnel control. In addition
to lacrimation, it causes eye pain, blepharospasm, eyelid
swelling, irritation of the conjunctiva, a rise in intraocular
pressure, and erythema of the skin. Because it can be used in
water, its use is less affected by changes in climatic conditions.
It is a more potent lacrimator than CS but it is less potent in
lethality than CS. |
