Caffeine Chemical Formula

Caffeine is a purine alkaloid and a trimethyl xanthine that acts as a stimulant for the Central Nervous System (CNS). Its chemical formula is C₈H₁₀N₄O₂ and is also termed methyl theobromine, 1,3,7-Trimethylxanthine, 7-methyltheophylline, guaranine, or theine.

Caffeine is an odorless white crystalline purine and has a bitter taste. Caffeine is a methylxanthine alkaloid that occurs naturally in the seeds, leaves, and fruit of several plants and trees native to Africa, East Asia, and South America. It can be synthesized by the reaction between dimethylurea and malonic acid. Caffeine is derived naturally from purine xanthine, which is present in more than sixty plants, including coffee, tea, and cocoa. It is the most often-used psychoactive substance worldwide. There are both positive and negative health impacts of caffeine. After repeated daily use, caffeine can cause a moderate form of drug dependence. So, when an individual stops using it after repeated use, it results in symptoms like sleepiness, headaches, and irritability.

In this article, we will learn about, Caffeine, Chemical Composition of Caffeine, Structure of Caffeine, Sources of Caffeine, Synthesis of Caffeine, etc, and others in detail.

What is Caffeine?

Caffeine is an Alkaloid and it acts as a chemical stimulant. Its IUPAC name is 1,3,7 – trimethylxanthine. Caffeine is naturally found in various compounds, the most common compound in which the caffeine is found is, Coffee Beans. It is soluble in warm water or hot water but partially soluble in water(at room temperature). It mealting point is 235-238°C and it is generally odorless and its in powered form.

Chemical Composition of Caffeine

Chemical Composition of Caffiene is C₈H₁₀N₄O₂. And its chemical composition is, it has 8 carbon atoms, 10 Hydrogen atoms, 4 Nitogen atoms, and 2 Oxygen atoms.

Caffeine Chemical Name

The chemical name of the caffeine is 1,3,7-Trimethylpurine-2,6-Dione.

Structure of Caffeine

The chemical formula of caffeine is C₈H₁₀N₄O₂, i.e., it is composed of eight carbon atoms, ten hydrogen atoms, four nitrogen atoms, and two oxygen atoms. The structure of caffeine is similar to that of the purine ring. Caffeine is a trimethylxanthine that is composed of two fused pyrimidinedione and imidazole rings and has three methyl groups located at positions 1, 3, and 7. Pyrimidinedione rings and imidazole rings are heterocyclic rings, where a pyrimidinedione ring is a 6-member ring with two nitrogen atoms, and an imidazole ring is a 5-member ring with two nitrogen atoms.

Sources of Caffeine

Various source of the that are found naturally are, sone leaves, fruits, and beans. And the primary source of the caffeine is coffee beans. It is also found in coca seeds, tea leaves, and kola nuts.

Synthesis of Caffeine

Caffeine is prepared by following the points added below,

• Caffeine is a methylxanthine alkaloid that occurs naturally in the seeds, leaves, and fruit of several plants and trees native to Africa, East Asia, and South America. 
• It can be synthesized by the reaction between dimethylurea and malonic acid.
• It can also be produced when theobromine is treated with methyl iodide and sodium methoxide.
• When uric acid is treated with methyl iodide in an alkaline solution, it produces 1,3,7-trimethyluric acid. On heating this further with phosphoryl chloride (POCl₃), it produces chlorocaffeine, which forms caffeine on further reduction with hydrogen iodide. 

• Caffeine is produced as a by-product in the manufacture of decaffeinated coffee by decaffeination. In the process of decaffeination, caffeine and decaffeinated coffee are produced by extracting caffeine from its natural sources, like coffee.

• Caffeine is used in energy drinks, soft drinks, and other beverages.

Side Effects of Caffeine

Various side effects of the caffeine are,

• Overdosage of caffeine may result in caffeine intoxication, which is a state of overstimulation of the central nervous system. It is a clinically significant, temporary condition that develops during or shortly after consuming caffeine.
• A high intake of caffeine in energy drinks was associated with short-term cardiovascular adverse effects.
• Ingestion of more than 400mg of caffeine per day may lead to sleeplessness, anxiety, restlessness, stomach discomfort, nausea, an elevated pulse, respiratory symptoms, headaches, stress, agitation, hyperventilation, hallucinations, diuresis, and bleeding disorders.
