Caffeine Formula

Caffeine Formula

Caffeine, also known as IUPAC name 1, 3, 7-trimethylpurine-2,6-dione, has the chemical formula C8H10N4O2 . Caffeine may be present in a variety of everyday foods and beverages, including coffee and tea. Coffee and tea leaves contain up to 5% caffeine. Caffeine is produced in chemical laboratories by the interaction of dimethylurea with malonic acid. In this article, we will learn more about caffeine’s chemical formula, chemical and physical characteristics, and chemical structure.

What is Caffeine Formula?

Caffeine is an alkaloid that serves as a chemical stimulant. The IUPAC name is 1,3,7-trimethylxanthine. Caffeine is present naturally in a variety of substances, the most prevalent of which being coffee beans. It is soluble in warm or hot water, but only partially so in water (at room temperature). It has a melting point of 235-238°C, is normally odourless, and is available in powered form.

Structure of caffeine

The representation of Caffeine Formula is a purine-like heterocycle. Positions 2 and 6 are carbonyl groups, and positions 1, 3, and 9 are methyl groups. The main source of Caffeine is coffee beans. Apart from that, it is also found in cacao, tea tree, and kola nut. Coffee beans are one of the most common sources of caffeine, and many people drink coffee regularly for the effects of caffeine.

Caffeine Chemical Formula

The chemical names for Caffeine are trimethylxanthine, mateine, theine, galanine, and methyl theobromine. It has a sour taste and a density of 1.23 gmL1. It has a melting point of 235°C and a boiling point of 178°C. Caffeine is easily soluble in water and liquids. It is a CNS (central nervous system) booster.  The implied response reversibly prevents the action of adenosine at specific receptors, thereby strengthening the nervous system. The caffeine molecule can function in this way because its structure is very similar to that of the adenosine molecule, especially as far as the nitrogenous base adenine is concerned. Due to their similarity, they are especially functionally equivalent to the nitrogenous base adenine. Students can visit the Extramarks website for Caffeine Formula.

FAQs (Frequently Asked Questions)

1. How is Caffeine prepared from Uric Acid?

When uric acid is mixed with methyl iodide in an alkaline solution, it forms 1,3,7-trimethyluric acid. Heating this with phosphoryl chloride (POCl3) creates chlorocaffeine, which is then reduced with hydrogen iodide to make caffeine.


2. What is the Chemical Formula Structure of Caffeine?

Caffeine has the chemical formula C8H10N4O2, meaning it is made up of eight carbon atoms, ten hydrogen atoms, four nitrogen atoms, and two oxygen atoms. Caffeine’s structure is comparable to the purine ring.


3. What colour is caffeine?

Caffeine occurs as a white, crystalline solid. However, it is most commonly found in dark or black foods and beverages like chocolate, coffee, and tea.
