36734-19-7 Usage

Uses

Different sources of media describe the Uses of 36734-19-7 differently. You can refer to the following data:
1. Fungicide.
2. Iprodione is a non-systemic fungicide that exhibits both protectant and eradicant activities against the spores and mycelium of a number of parasitic fungi. It is effective against Alternaria, Botrytis, Corticium, Fusarium, Helminthosporium, Monilinia, Phoma, Pleiochaeta, Rhizoctonia and Sclerotinia, etc. in nut crops, fruit trees (stone and pome fruit), vines, berries, vegetables, cereals, oilseed rape, cotton and ornamentals. Iprodione also controls various summer and winter turf diseases.

Definition

ChEBI: An imidazolidine-2,4-dione in which the nitrogen at position 1 is substituted by an N-(isopropyl)carboxamide group while that at position 3 is substituted by a 3,5-dichlorophenyl group. A contact fungicide, it blocks the growth of the fu gal mycelium and inhibits the germination of fungal spores. It is used on fruit and vegetable crops affected by various fungal diseases. It is also used as a nematicide.

Safety Profile

Moderately toxic by ingestion. When heated to decomposition it emits very toxic fumes of NOx and Cl-.

Environmental Fate

Soil. Readily degrades in soil (half-life 20 to 160 days) releasing carbon dioxide 3,5dichloroaniline (Walker, 1987) and (Hartley and Kidd, 1987; Worthing and Hance, 1991). The rate of degradation increases with repeated applications of this fungicide. In a clay loam, the half-life was 1 week. After the second and third applications, the half-lives were 5 and 2 days, respectively (Walker et al., 1986).Plant. Translocation and uptake by potato plants were reported (Cayley and Hide, 1980). Iprodione is rapidly metabolized in plants to 3,5-dichloroaniline (Cayley and Hide, 1980; Hartley and Kidd, 1987).Chemical/Physical. In an aqueous solution at pH 8.7, iprodione hydrolyzed to N-(3,5dichloroanilinocarbonyl)-N-(isopropylaminocarbonyl)glycine (Belafdal et al., 1986). At pH 8.7, complete hydrolysis occurred after 14 hours (Cayley and Hide, 1980).Gomez et al. (1982) studied the pyrolysis of iprodione in an helium atmosphere at 400–1,000°C. Decomposition began at 300°C producing isopropyl isocyanate and 3-(3,5dichlorophenyl)hydantoin. Above 600°C, the hydantoin ring began to decompose forming the following products: 3-chloroaniline, 3,5-dichloroaniline, chlorinated benzenes and benzonitrile. From 800 to 1,000°C, the hydantoin ring was completed destroyed whichled to the formation of aryl isocyanates, anilines and the corresponding diarylureas, namely 3-(3,5-dichlorophenyl)urea and 1-(3-chlorophenyl)-3-(3,5-dichlorophenyl)urea (Gomez et al., 1982).

Metabolic pathway

The opening and rearrangement of the dioxoimidazolidine ring is the initial and major degradation/metabolic reaction for iprodione. Iprodione degrades in soil via cleavage of the dioxoimidazolidine-carboxamide linkage, followed by ring opening to yield 3,5-dichloroaniline and CO2. In plants and animals, primary degradation reactions include N-dealkylation of the isopropyl moiety, ring opening and aryl hydroxylation (Scheme 1).

Degradation

Iprodione (1) is stable in acidic solution (< pH 5) and degraded rapidly in alkaline solution with DT50 values of 37 days, 1.1 days and 21 min at pH 5, 7 and 9 at 25 °C, respectively (Melkebeke et al., 1986). Opening of the oxazolidinedione ring yielded N-(3,5-dichloroanilinocarbonyl)-N- (isopropylaminocarbonyl)glycine (2) (Belafdal et al., 1986). This reaction involves the attack of a hydroxyl ion on the carbonyl moiety in the 4-position of the hydantoin ring. Laurent (1974a, 1976a) and Das (1990) reported the further dehydration/rearrangement of compound 2 to yield an iprodione isomer (3). Iprodione degraded readily in water under UV light irradiation (Laurent, 197413) but was relatively stable when exposed to simulated sunlight (Adrian and Robles, 1991). The degradation of iprodione in aqueous solution proceeded via various mechanisms including isomerisation, dechlorination, hydrolysis and hydroxylation. Schwack et al. (1995) and Schwack and Bourgeois (1989) reported that dechlorination was the primary photodegradation reaction when iprodione in various organic solvents (e.g. isopropanol) was irradiated with UV light (>280 nm). Other photodegradation reactions included the replacement of the chlorine atom by the solvent molecule.

Check Digit Verification of cas no

The CAS Registry Mumber 36734-19-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,6,7,3 and 4 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 36734-19:
(7*3)+(6*6)+(5*7)+(4*3)+(3*4)+(2*1)+(1*9)=127
127 % 10 = 7
So 36734-19-7 is a valid CAS Registry Number.
