ALDICARB-OXIME

The Uses of ALDICARB-OXIME

Temik Oxime is an intermediate in the synthesis of Aldicarb-d3 Sulfoxide (A514667), which is a labeled Aldicarb Sulfoxide (A514665). Aldicarb Sulfoxide is an analog of Aldicarb (A514650) detected in agricultural products as pesticide residue.

Definition

ChEBI: The oxime resulting from the formal condensation of 2-methyl-2-(methylsulfanyl)propanal with hydroxylamine. Addition of the oxime group to methyl isocyanate forms the final step in the synthesis of the systemic insecticide aldicarb.

General Description

Clear colorless,viscous liquid with an unpleasant sulfurous or musty odor.

Air & Water Reactions

Sensitive to heat. Water soluble. May decompose with prolonged exposure to moisture.

Reactivity Profile

ALDICARB-OXIME is incompatible with oxidizers, acids and alkalis [(NTP, 1992]. Several explosions or violent decompositions have occurred during distillation of alkoxides, which may be attributable to the formation of peroxides of various types. This is especially the case in the presence of acid, Chem. Eng. News, 1974, 52(35), 3. A nickel catalyzed aldoxime rearrangement to an amide, went out of control after changing the solvent employed, J. Loss Prev., 1993, 6(2), 69.

Fire Hazard

ALDICARB-OXIME is combustible.
