説明
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.
-
化学的特性
Metolcarb is a colorless crystalline
solid.
-
使用
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.
-
製造方法
Metolcarb is produced by the reaction between 3-
methylphenol and Metolcarb.
-
一般的な説明
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.

空気と水の反応
Soluble in water.

反応プロフィール
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.
-
健康ハザード
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.
-
火災危険
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.

職業ばく露
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.

代謝経路
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.

不和合性
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.
