N-Ethyl perfluorooctylsulfonamide (sulfluramid)

Name of Chemical: HX-12

Molecular Formula: C10H6F17O2NS

Molecular Weight: 527

Characters: light-yellow solid, melting, point is 88-90°C,it can have reactions with chlorethanol and chloracetate, can dissolve in alcohol, acetone and other organic solvent and appears amber.

Uses: sulfluramid is a new kind of organo-fluorine pesticide and has good effects. It is mainly used to prevent ant, cockroach and other reptile insects. Nanjing Military Medicine Research Institute and Nanjing University have carried out the following toxicity test:
1, experimental insects: small adult cockroach of Germany;
2, test procedure: prepare sulfluramid as the concentrations of 2%, 1%, 0.5%, 0.25%and 0.125% with acetone. Take the cockroach with a test tube, anesthetize them lightly with diethyl ether, list them with upper belly, use  10µ I sample  injector  to  absorb  2µ  I medical  liquid  and  drip them  on the belly between the second pair of  feet and the third pair of  cockroach . Repeat  this  from low  concentration to high  concentration  and  take  acetone  drop as the contrast ;
3, test conclusion is shown as the follows:
    sulfuramid to Germany  cockroach:      24hLD50=10.8X10-3µ g/cockroach,
    48 hLD50= 9.7X10-3 µ g/cockroach,       72hLD50=4.0 X10-3µ g/cockroach,
    96hLD50= 1.3 X10-3 µ g/cockroach,
