The Upstream and Downstream products of 1,1'-THIOCARBONYLDI-2(1H)-PYRIDONE

1,1'-Thiocarbonyl-di-2(1H)-pyridone, also known as thiocarbamide, is an organic compound with the chemical formula C4H4N2S2.
It is a white or slightly yellowish solid with a characteristic odor.
Thiocarbamide is widely used in the chemical industry as an intermediate in the production of a variety of chemicals and pharmaceuticals.

Upstream Products
The upstream products of thiocarbamide are the raw materials that are used to produce it.
These materials are typically derived from petrochemical or natural sources and are converted into intermediate compounds through a series of chemical reactions.
The upstream products of thiocarbamide include ethyl, propyl, and butyl chloride, which are used as building blocks for the synthesis of thiocarbamide.

Downstream Products
The downstream products of thiocarbamide are the chemicals and pharmaceuticals that are produced using thiocarbamide as an intermediate.
These products are derived from thiocarbamide through a series of chemical reactions, such as polymerization, alkylation, and condensation reactions.
The downstream products of thiocarbamide include a wide range of chemicals, such as herbicides, insecticides, fungicides, and pharmaceuticals.

One of the most common downstream products of thiocarbamide is the herbicide known as atrazine.
Atrazine is a broad-spectrum herbicide that is used to control weeds in a variety of crops, including corn, soybeans, and wheat.
Atrazine works by inhibiting the growth of plants, leading to their eventual death.
Atrazine is one of the most widely used herbicides in the world, and it is derived from thiocarbamide through a series of chemical reactions.

Another downstream product of thiocarbamide is the pharmaceutical drug called metoclopramide.
Metoclopramide is used to treat a variety of gastrointestinal disorders, such as nausea, vomiting, and gastroesophageal reflux disease (GERD).
It works by increasing the contractions of the stomach and intestines, which helps to move food through the digestive system more quickly.
Metoclopramide is derived from thiocarbamide through a series of chemical reactions.

Thiocarbamide is also used as an intermediate in the production of other pharmaceutical drugs, such as antihistamines, anti-anxiety medications, and sedatives.
These drugs are derived from thiocarbamide through a series of chemical reactions that involve the introduction of functional groups onto the thiocarbamide molecule.

Chemical Reactions Used in the Production of Downstream Products
The production of downstream products from thiocarbamide typically involves a series of chemical reactions that are designed to introduce new functional groups onto the thiocarbamide molecule.
These reactions can include alkylation, polymerization, condensation, and other reactions that involve the introduction of new functional groups.

In the case of the production of atrazine, the thiocarbamide molecule is first treated with chlorine to create a chlorinated derivative.
This derivative is then treated with a compound known as a tin compound to introduce a new functional group onto the molecule.
This process is known as Tishchenko modification, and it is commonly used in the production of herbicides.

In the case of the production of metoclopramide, the thiocarbamide molecule is treated with a variety of reagents
