METOLCARB

Описание

Metolcarb (17), m-tolyl methylcarbamate (IUPAC), C9H11NO2, MW 165.2, mp 76–77 ?C, is a colorless solid that is moderately soluble in water and is readily soluble in polar organic solvents.

Химические свойства

Metolcarb is a colorless crystalline solid.

Использование

Metolcarb is used to control planthoppers, leafhoppers and other sucking pests on rice. It is also used for control of citrus mealybugs, onion thrips, Mediterranean fruit flies, pink bollworms and cotton aphids.

Подготовка

Metolcarb is produced by the reaction between 3- methylphenol and Metolcarb.

Общее описание

Colorless crystalline solid. METOLCARB is an insecticide for the control of rice leafhoppers, planthoppers, codling moth, citrus mealybug, onion thrips, fruit flies, bollworms and aphids. Not registered as a pesticide in the U.S.

Реакции воздуха и воды

Soluble in water.

Профиль реактивности

METOLCARB is a carbamate ester. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates.

Угроза здоровью

High oral and skin toxicity, and moderate inhalation toxicity. (Non-Specific -- Carbamates) Some carbamates appear to be carcinogenic, teratogenic, and/or mutagenic. Carbamates are cholinesterase inhibitors.

Пожароопасность

As for other solid carbamate pesticides, container may explode in heat of fire. Fire and runoff from fire control water may produce irritating or poisonous gases. Emits toxic fumes of nitrogen oxides when heated to decomposition. Avoid decomposing heat.

Metolcarb is an insecticide used for the control of rice leafhoppers, plant-hoppers; codling moth; citrus mealy bug; onion thrips; fruit flies; bollworms and aphids. Not registered as a pesticide in the United States.

Метаболический путь

The main pathways of metabolism of metolcarb in plants, mammals and insects involve ring-methyl, N-methyl and phenyl-ring hydroxylation and conjugation. Carbamate ester hydrolysis is a minor reaction. Further oxidation of a ring-hydroxymethyl moiety to carboxyl occurs in rats and insects.

Несовместимости

Carbamates are incompatible with reducing agents such as hydrides, strong acids, oxidizing acids, peroxides, and bases. Contact with active metals or nitrides cause the release of flammable, and potentially explosive, hydrogen gas. May react violently with bromine, ketones. Incompatible with azo dyes, caustics, ammonia, amines, boranes, hydrazines, strong oxidizers.

Утилизация отходов

Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform to EPA regulations governing storage, transportation, treatment, and waste disposal. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
