(3-Chloropyrazin-2-yl)MethanaMine Hydrochloride, also known as Valsartan, is an antihypertensive drug that is widely used to treat high blood pressure and heart failure.
It is a white to off-white crystalline powder with a molecular formula of C15H12ClN3O3S•HCl.
The molecule has a polar surface area of 83.
16 Ų, and a calculated molecular weight of 408.
8.
The upstream products of (3-Chloropyrazin-2-yl)MethanaMine Hydrochloride are the raw materials needed to manufacture the drug.
These include chemicals such as chloropyrazine, methylamine, and hydrochloric acid.
The chloropyrazine is synthesized by nitrating pyrazine with nitric acid, and then reduction with hydrogen in the presence of a catalyst such as palladium on barium sulfate.
Methylamine is produced by the gas-phase reaction of methyl iodide with ammonia, or by the hydrolysis of methyl iodide with water.
Hydrochloric acid is commonly produced by the absorption of hydrogen chloride gas in water, or by the reaction of sodium chloride with hydrogen peroxide.
Once these upstream products have been obtained, they are then utilized in the manufacturing process of (3-Chloropyrazin-2-yl)MethanaMine Hydrochloride.
The manufacturing process involves several steps, including synthesis, purification, and formulation.
The synthesis step involves the reaction of chloropyrazine and methylamine in the presence of a solvent such as dimethylformamide and a base such as triethylamine.
This reaction results in the formation of (3-chloropyrazin-2-yl)methylamine, which is then hydrolyzed in the presence of hydrochloric acid to produce (3-chloropyrazin-2-yl)MethanaMine Hydrochloride.
The resulting product is then purified through a series of chromatography steps, which involve the use of techniques such as high-performance liquid chromatography (HPLC) and recrystallization to obtain a pure sample of the drug.
The final step in the manufacturing process is formulation, which involves mixing the drug with other ingredients such as excipients and fillers to produce the final product.
The downstream products of (3-Chloropyrazin-2-yl)MethanaMine Hydrochloride are the final product that is used by patients and the various forms and dosages that are available.
The final product is a white to off-white crystalline powder that is soluble in water and ethanol.
The drug is available in various forms and dosages, including tablets, capsules, and suspensions.
Each of these forms and dosages has its own unique characteristics, such as the amount of drug per dose, the release rate, and the method of administration.
(3-Chloropyrazin-2-yl)MethanaMine Hydrochloride is considered a Class III drug in the United States, which means that it is not approved for use in humans or animals.
However, the drug is widely used in other countries for the treatment of hypertension and heart failure.
It is sold under various brand names, including Diovan, Valturna, and Exforge.
The drug is also available in various generic formulations, which are sold at a lower price than the branded versions.
In conclusion, (3-Chloropyrazin-2-yl)MethanaMine Hydrochloride is an important antihypertensive drug that is used to treat high blood pressure and heart failure.
The upstream products for the manufacture of the drug include chloropyrazine, methylamine, and hydrochloric acid, while the downstream products include various forms and dosages of the final product.
The manufacturing process of the drug involves several steps, including synthesis, purification, and formulation.
The drug is widely used in other countries, but is not approved for use in the United States.
