Chemical structure and physical properties of Nicotinamide Capsules

Nicotinamide, also known as niacinamide or nicotinic acid amide, is a form of vitamin B3 (niacin). It is often used in dietary supplements and medications due to its various health benefits. Nicotinamide capsules typically contain nicotinamide as the active ingredient along with other inert substances to form the capsule. Here’s an overview of its chemical structure and physical properties:

Chemical Structure:

Nicotinamide has the chemical formula C6H6N2O.

It is an amide derivative of nicotinic acid (niacin).

The chemical structure consists of a pyridine ring with an amide functional group attached to the carbon in the ring.

Physical Properties:

Appearance: Nicotinamide typically appears as a white, crystalline powder.

Melting Point: The melting point of nicotinamide is approximately 128-131°C.

Solubility: It is freely soluble in water and ethanol.

Odor and Taste: Nicotinamide is odorless and has a slightly bitter taste.

Stability: It is stable under normal conditions of storage and handling.


Absorption: Nicotinamide is readily absorbed from the gastrointestinal tract.

Distribution: It is distributed widely throughout the body tissues.

Metabolism: Nicotinamide is metabolized primarily in the liver.

Excretion: Metabolites are excreted in urine.

Health Benefits:

Nicotinamide is essential for the synthesis of nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP), which are coenzymes involved in various metabolic pathways.

It has been used to treat or prevent niacin deficiency and its associated conditions such as pellagra.

Nicotinamide has also been studied for its potential benefits in skincare, particularly in reducing the appearance of hyperpigmentation and improving skin barrier function.
