English description（英文原文，共 993 字符）
Product Name:Metam-sodium
English Name:Metam-sodium
CAS No.:137-42-8
Aliases:Sodium methyldithiocarbamate, Methylcarbamodithioic acid sodium salt
Molecular Formula:C2H4NNaO2S2
Physical Properties:White crystalline solid in pure form, readily soluble in water; aqueous solution is alkaline. Industrial product is usually a reddish-brown transparent liquid. Decomposes under acidic conditions to generate methyl isothiocyanate (MITC), providing fumigant activity.
Uses:A soil fumigant disinfectant used for controlling nematodes and soilborne diseases on peanuts, cotton, soybeans, potatoes, melons and fruits. After application to soil, it decomposes to release methyl isothiocyanate (MITC), which effectively kills nematodes, plant pathogens and weed seeds in soil.
Technical Specifications:
Content: ≥35% aqueous solution (industrial grade)
Molecular weight: 161.18
Melting/decomposition point: approx. 100°C
pH value (as supplied): 8.0–9.5
Density (20°C): approx. 1.09–1.17 g/cm³
