THIOUREA PURIFIED
Thiourea are organic compounds having a carbon atom bonded to two amine groups. The key difference between urea and thiourea is that urea does not contain sulfur atoms, whereas thiourea contains sulfur atoms. Thiourea is able to prevent or reverse interstrand crosslinking by cisplatin in purified DNA.
Thiourea is used as an auxiliary agent in diazo paper, light-sensitive photocopy paper and almost all other types of copy paper. It is also used to tone silver-gelatin photographic prints.
Thiourea, also called thiocarbamide, an organic compound that resembles urea (q.v.) but contains sulfur instead of oxygen; i.e., the molecular formula is CS(NH2)2, while that of urea is CO(NH2)2.
In thiourea, a double bond is present between the carbon and sulfur atom. So, it is an unsaturated compound. Hence, thiourea is an unsaturated compound.

Dissolve 500 mg 6-chloro-A in 5ml ethanol, add 1.5 equivalents of thiourea and reflux for 1 hour. After the reaction cools down i remove the filtrate and concentrate the flow-though.
Thiourea, also chemically named as Thiocarbamide, is a nitrogen and sulfur containing compound. It has three functional. groups, amino, imino and thiol, each with important biological roles.
Thiourea is an inhibitor which prevents chemical attack on the metal itself. If thiourea is not used in the treatment solution dissolved copper will be redeposited on the surface of the object, leaving a salmon pink blush on the surface. This then has to be removed by polishing.
Thiourea PRACT is a white crystalline solid, both naturally occurring and synthetic, that is soluble in water, ammonium thiocyanate solution and ethanol. In the past, it was used as a photographic toning agent, a component of hair preparations and a dry cleaning agent.
Cleaning copper objects
Cleaning Procedure of copper objects:
THIOUREA AR is used in vulcanization accelerators. It is used as an auxiliary agent. It is used in silver – gelatin photographic prints. It is used in diazo paper, light – sensitive photocopy paper.
Thiourea are organic compounds having a carbon atom bonded to two amine groups. The key difference between urea and thiourea is that urea does not contain sulfur atoms, whereas thiourea contains sulfur atoms.
The percentages of nitrogen and sulfur in all the samples synthesized from thiourea were roughly 5–20 wt. % and 3–8 wt. % even after washing with hot water, respectively.
