Properties and stability

1. Basic properties

White or light yellow needle-like or rhombohedral crystals. Easily soluble in methanol, ethanol, acetic acid, acetone and alkali, soluble in about 30 parts of boiling water, slightly soluble in cold water, very slightly soluble in dilute mineral acid, insoluble in ether and ethyl acetate. Melting point ≥300℃. Toxic, LD50 (�Rat, oral) 155mg/kg.

Storage method

2. Storage:

Seal and store in a dark place.

Synthesis method

1. Obtained from nitration of p-hydroxyphenylarsonic acid. Add p-hydroxyphenylarsonic acid and sulfuric acid into the reaction pot, stir and cool to below 0°C, slowly add the mixed acid, continue stirring for 1 hour, put it into ice water to precipitate, filter and dry to obtain 4-hydroxy-3-nitrobenzene Arsinic acid.

2.It is prepared from p-hydroxyaniline as raw material through diazotization, arsenization and nitration; it can also be made from phenol as raw material through arsenization and nitration be made of.

Purpose

1. Used as an intermediate in organic synthesis and a reagent for the determination of cadmium. The oral LD50 in rats is 155 mg/kg

2.Broad-spectrum antibacterial and antiprotozoal drugs. It can improve feed efficiency, promote growth, prevent and treat various bacterial and protozoal diseases, and promote pigmentation and ketone body quality.
