| Chemical Properties | Cyhexatin is a colorless to white, nearly odor-less, crystalline powder. |
| Uses | Cyhexatin is a derivative of tricyclohexyltin and an effective acaricide used in the control of spider mites. |
| Uses | Acaricide. |
| Uses | Cyhexatin is used to control the motile stages of phytophagousmites on pome and stone fruit, vines, hops, cotton, vegetables andornament ah. |
| Definition | ChEBI: Cyhexatin is an organotin acaricide. |
| General Description | Technical Cyhexatin is a nearly odorless white crystalline powder that has no true melting point but degrades to bis(tricyclohexyl)tin oxide at 121 to 131°C which decomposes at 228°C; a melting point of 195-198°C is also reported. Very insoluble in water (less than 1 mg/L at 25°C), but wettable by water. Soluble in some organic solvents (acetone 1.3 g/L; xylenes 3.6 g/L; carbon tetrachloride 28 g/L; dichloromethane 34 g/L). Used as an acaricide (an agent to kill plant-feeding mites) in almonds, walnuts, hops and some fruits. |
| Reactivity Profile | Cyhexatin is incompatible with strong oxidizing agents. Soluble in some organic solvents (acetone 1.3 g/L; xylenes 3.6 g/L; carbon tetrachloride 28 g/L; dichloromethane 34 g/L). Stable in aqueous suspensions in neutral and alkaline pH (above pH 6), but reacts exothermically as a base in the presence of strong acids to form salts. Converts to dicyclohexyltin oxide and further to cyclohexylstannoic acid upon exposure to ultraviolet radiation. |
| Safety Profile | Poison by ingestion, inhalation, and intraperitoneal routes. Moderately toxic by skin contact. Experimental reproductive effects. When heated to decomposition it emits acrid smoke and irritating fumes. See also TIN COMPOUNDS. |
| Potential Exposure | Used as an agricultural chemical andpesticide. A potential danger to those involved in the manu-facture, formulation, and application of this acaricide(miticide). |
| First aid | If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Speed in removing material from skinis of extreme importance. Shampoo hair promptly if contaminated. Seek medical attention immediately. If thischemical has been inhaled, remove from exposure, beginrescue breathing (using universal precautions, includingresuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit. |
| Metabolic pathway | There is little published information of the degradation and metabolismof cyhexatin. However, useful information on the fate of cyhexatin in awater/sediment system can be deduced from published data onazoc yclotin. |
| storage | Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with thischemical you should be trained on its proper handling andstorage. Store in tightly closed containers in a cool, dark,well-ventilated area away from oxidizers. |

| Degradation | Cyhexatin is stable to hydrolysis at temperatures up to 100 °C fromslightly acid (pH 6) to alkaline conditions (PM). |
| Incompatibilities | Incompatible with strong oxidizers. Mayreact exothermically as base in the Incompatible withstrong oxidizers. May react exothermically as base in theIncompatible with strong oxidizers. Reacts exothermicallyas base in the presence of strong acids, forming salts. Keep away from ultraviolet radiation which may cause conver-sion to dicyclohexyltin oxide and further to cyclohexylstan-noic acid. |
