900-95-8 Usage
Uses
Different sources of media describe the Uses of 900-95-8 differently. You can refer to the following data:
1. Triphenyltin Acetate is an organotin compound. Triphenyltin Acetate much like its hydroxide analogue is used as a fungicide and antifeeding compound for insect control. Recent studies show that Triphenyltin Acetate may have adverse effects on the reproductive and immune systems and may disrupt the endocrine system.
2. Fentin is a non-systemic fungicide with protective and curative
action. It is used to control early and late blight in potatoes and a range of
diseases in vegetables, sugar beet, peanuts, wheat, coffee, cocoa and
pecans. It is also used to control algae and snails in rice fields. Fentin has
previously been used as an antifoulant in marine paint.
Definition
ChEBI: An organotin compound that is the O-acetyl derivative of triphenyltin hydroxide. A fungicide used to control blights on potatoes, leaf spot diseases on sugar beet and anthracnose on beans.
General Description
A white crystalline solid. Melting point 123-131°C (253-268°F). Used as a fungicide, algaecide and molluscicide. Controls early and late blight on potatoes.
Air & Water Reactions
Slowly oxidized, hydrolyzed when exposed to air and moisture.
Reactivity Profile
ACETOXYTRIPHENYLSTANNANE is subject to decomposition when exposed to air, light and moisture [EPA, 1998].
Health Hazard
Very toxic, irritant to skin.
Fire Hazard
Avoid air, light and moisture.
Safety Profile
Poison by ingestion, intraperitoneal, intravenous, and subcutaneous routes. Moderately toxic by skin contact. Questionable carcinogen with experimental neoplastigenic data. An experimental teratogen. Other experimental reproductive effects. A fungicide and algicide used as a wood preservative. When heated to decomposition it emits acrid smoke and Sn' fumes. See also TIN COMPOUNDS.
Metabolic pathway
Fentin is degraded in soil and other biological media to give inorganic tin
via the di- and mono-phenyltin compounds; often the resulting benzene is
liberated. An extensive review on the metabolism and fate and behaviour
of triphenyltin and its degradation products was published by Bock
(1981). Fentin hydroxide has been the subject of an evaluation by the
Pesticide Safety Directorate of UK MAFF (PSD, 1990).
Degradation
Fentin acetate is stable when dry but easily hydrolysed to fentin hydroxide
in the presence of water. It is unstable in acids and alkalis (DT50 <3
hours at pH 5, 7 or 9; 22 °C) and ionises to the triphenyltin cation. Triphenyltin
compounds are converted rapidly and quantitatively into the
hydroxide by alkali. Diphenyltin compounds (2) (see Scheme 1) react
similarly but the hydroxide quickly loses water forming the oxide.
Diphenyltin chloride initially hydrolyses to (C6H5),Sn(OH)Cl which
forms compound 3 when dissociated and then the oxide is formed via
dimeric intermediates. Diphenyltin compounds also split off phenyl
groups as benzene (4) under the influence of water, acids or bases.
Monophenyltin compounds (5) are also converted by alkali into the
hydroxide which immediately loses water to form phenylstannonic acid
(C6H5SnOOH) (6). In aqueous solution and at room temperature, triphenyltin
compounds decompose at a slow rate, losing phenyl groups as
benzene. The acetate is decomposed by sunlight and atmospheric oxygen.
Phenyltin compounds are slowly decomposed by sunlight and more
rapidly by UV light to give inorganic tin via the di- and mono-phenyltin
compounds (PM; Bock, 1981).
Check Digit Verification of cas no
The CAS Registry Mumber 900-95-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,0 and 0 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 900-95:
(5*9)+(4*0)+(3*0)+(2*9)+(1*5)=68
68 % 10 = 8
So 900-95-8 is a valid CAS Registry Number.
