| tubocurarine chloride | C38H44Cl2N2O6-5H 2O; d-Tubocurarine chloride;an alkaloid (obtained from the stems of Chondodendron, particularly C. Tomentosum) that blocks the action of acetylcholine at the myoneural junction by occupying the receptors competitively; also blocks ganglionic transmission and releases histamine; used to produce muscular relaxation during surgical operations. (05 Mar 2000) |
| ethyl chloride | <chemical> A gas that condenses under slight pressure. Because of its low boiling point ethyl chloride sprayed on skin produces an intense cold by evaporation. Cold blocks nerve conduction. Ethyl chloride has been used in surgery but is primarily used to relieve local pain in sports medicine. Pharmacological action: anaesthetics, local. Chemical name: Ethane, chloro- (12 Dec 1998) |
| ethylmercuric chloride | <chemical> A highly toxic compound used as a fungicide for treating seeds. Pharmacological action: fungicides, industrial. Chemical name: Mercury, chloroethyl- (12 Dec 1998) |

| zinc chloride | ZnCl2;formerly used as a caustic for the removal of cutaneous cancers, nevi, etc., and in weak solution in the treatment of gonorrhoea and conjunctivitis. Synonym: butter of zinc. (05 Mar 2000) |
| ferric chloride | An astringent and styptic. (05 Mar 2000) |
| ferric chloride reaction of epinephrine | An intense emerald green colour in a neutral or slightly acid solution of epinephrine when ferric chloride is added to it; a reaction typical of catechols. (05 Mar 2000) |
| ferric chloride test | A qualitative test for the detection of phenylketonuria; the addition of ferric chloride to urine gives rise to a blue-green colour in the presence of phenylketonuria. (05 Mar 2000) |
