RARECHEM AL BO 0444 - Introduction
(4-CARBOXYPHENYL)THIOUREA, also known as (4-CARBOXYPHENYL)THIOUREA, is an organic compound. Its molecular formula is C8H6N2O2S.
Nature:
(4-CARBOXYPHENYL)THIOUREA is a colorless crystal, soluble in most organic solvents and acidic aqueous solutions, but hardly soluble in water. It is acidic and can form salts and metal complexes. The compound is stable at room temperature.
Use:
(4-CARBOXYPHENYL)THIOUREA has certain practical value in the field of chemistry. It can be used as an intermediate in the synthesis of organic pigments, dyes and photosensitive substances. In addition,(4-CARBOXYPHENYL)THIOUREA is also used as an extraction and separation reagent for metal ions.
Method:
The preparation of (4-CARBOXYPHENYL)THIOUREA is usually obtained by oxidation of thiocyanothiourea (S-thiocyanic thiourea). First, thiocyanic acid is reacted with sodium carbonate in a suitable solution to form thiocyanatothiourea. This intermediate product then undergoes a series of oxidation reactions to give the final product (4-CARBOXYPHENYL)THIOUREA.
Safety Information:
(4-CARBOXYPHENYL)THIOUREA is relatively safe, but it is still necessary to pay attention to safe operation. It may be irritating to the eyes and skin. Wear appropriate protective equipment during use to avoid contact and inhalation. If contact with skin or eyes, rinse immediately with plenty of water and seek medical advice. When stored, it should be kept in a closed container, away from fire and oxidizing agents. Dispose of waste in accordance with local regulations.
