Toxicological data

1. Acute toxicity: Mouse (peritoneal) LD50: 1,930μg/kg; Mouse (intravenous) LDLo: 1,570μg/kg Mouse (not reported) LD50: 1,900μg/kg Rabbit (intravenous) LD50: 790mg/kg

Since the LD50 of table salt is 3,000 mg/kg, the acute toxicity of BPA is the same as that of table salt.

Ecological data

Extremely harmful to water, even in small amounts. Do not let this product come into contact with groundwater, waterways and sewage systems. Even a small amount of this product seeping into groundwater will cause danger to drinking water and is also toxic to fish and plankton in the water.��Highly toxic to organic matter in water. Do not discharge materials into the surrounding environment without government permission.

Properties and stability

Keep away from oxides.

Storage method

Store in an airtight container in a cool, dry place. The storage area must be locked and the keys must be given to the technical experts and their assistants. Store away from oxidizing agents.

Synthesis method

Mix benzene arsenic acid, methanol and concentrated hydrochloric acid in a weight ratio of 1:5:2, add a little potassium iodide, and then add sulfur dioxide until saturated. Dissolve the oily benzene arsenic chloride generated by the reaction with sodium hydroxide solution, and then neutralize it with hydrochloric acid to precipitate the benzene arsenic oxygen.

Purpose

Used in organic synthesis. This product is highly toxic and used as a pesticide.
