870196-80-8 - Introduction

4-Cyano-4-(sulfanylpentanoic acid), also known as DAS insecticide (DAS-1). It is an organophosphate insecticide. The following is a description of its nature, use, preparation and safety information:

Nature:
-Appearance: Colorless crystalline solid
-Molecular formula: C12H21NO4PS3
-Molecular Weight: 411.54
-Melting point: 60-62 ° C
-Boiling point: 375.6 ° C
-Solubility: Insoluble in water, soluble in organic solvents such as alcohols, ethers and ketones

Use:
DAS insecticides are mainly used in agriculture to control a variety of insect pests. It can be widely used in fruit trees, vegetables, corn and other crops to effectively control the reproduction and damage of pests.

Preparation Method:
4-Cyano-4-(the preparation method of sulfanylpentanoic acid) is as follows:
-First, reacting chlorosulfonyl sulfate and pentanediol to generate sulfate;
-Then, the sulfate ester is reacted with cyanic acid to generate tetracyano-1, 2-ethanedione;
-Finally, tetracyano-1, 2-ethanedione is reacted with dodecylthiamine to generate the target product 4-Cyano-4-(sulfanylpentanoic acid).

Safety Information:
- DAS insecticide is a highly toxic pesticide. Please use it strictly in accordance with the instructions for use and avoid contact with skin, eyes and respiratory tract.
-Wear appropriate personal protective equipment such as gloves, goggles and masks during use.
-It is prohibited to store, transport and use together with food, beverages and feed to be consumed.
-When handling and disposing of waste, please comply with local regulations to prevent pollution to the environment.
