Description
Cyhexatin, a derivative of tricyclohexyltin, is a colorless to white crystalline powder with nearly odorless properties. It is characterized by its low solubility in water and solubility in some organic solvents. Cyhexatin is known for its effectiveness as an acaricide, particularly in controlling spider mites and other plant-feeding mites.
Uses
Used in Agriculture:
Cyhexatin is used as an acaricide for controlling the motile stages of phytophagous mites on various crops, including pome and stone fruit, vines, hops, cotton, vegetables, and ornamental plants. It helps protect these plants from damage caused by mites, ensuring a healthy yield.
Used in Almond and Walnut Production:
Cyhexatin is employed as an acaricide in almond and walnut production, specifically targeting spider mites and other plant-feeding mites that can cause significant damage to these crops.
Used in Hops and Fruit Production:
Cyhexatin is also used in the production of hops and some fruits, where it serves as an effective agent to kill plant-feeding mites, thus protecting the quality and quantity of the harvest.
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 and
pesticide. A potential danger to those involved in the manu-
facture, formulation, and application of this acaricide
(miticide).
Metabolic pathway
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.

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

Check Digit Verification of cas no
The CAS Registry Mumber 13121-70-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,1,2 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 13121-70:
(7*1)+(6*3)+(5*1)+(4*2)+(3*1)+(2*7)+(1*0)=55
55 % 10 = 5
So 13121-70-5 is a valid CAS Registry Number.
