13121-70-5

Technical CYHEXATIN(13121-70-5) 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.

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.

Used as an agricultural chemical and pesticide. A potential danger to those involved in the manu- facture, formulation, and application of this acaricide (miticide).

Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respira- tion with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with run- ning water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion, or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Medical obser- vation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized para- medic may consider administering a drug or other inhala- tion therapy.

Incompatible with strong oxidizers. May react exothermically as base in the Incompatible with strong oxidizers. May react exothermically as base in the Incompatible with strong oxidizers. Reacts exothermically as 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 .

Cyhexatin is a colorless to white, nearly odorless, crystalline powder. Molecular weight=385.16;Boiling point=227℃(decomposes); Freezing/Meltingpoint=195-198℃. Practically insoluble in water

Cyhexatin is a colorless to white, nearly odor- less, crystalline powder.

Acaricide.

Cyhexatin is a derivative of tricyclohexyltin and an effective acaricide used in the control of spider mites.

Cyhexatin is used to control the motile stages of phytophagous mites on pome and stone fruit, vines, hops, cotton, vegetables and ornament ah.

ChEBI: Cyhexatin is an organotin acaricide.

There is little published information of the degradation and metabolism of cyhexatin. However, useful information on the fate of cyhexatin in a water/sediment system can be deduced from published data on azoc yclotin.

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.

Cyhexatin is stable to hydrolysis at temperatures up to 100 °C from slightly acid (pH 6) to alkaline conditions (PM).
