HPLC Method for Nicotinic Acid/Niacin (3-pyridinecarboxylic acid), Nicotinamide, Pyridinedicarboxylic Acid, 2,5-Pyridinedicarboxylic acid, 5-Ethyl-2-methylpyridine, Ethyl nicotinate on Primesep 100 by SIELC Technologies

High Performance Liquid Chromatography (HPLC) Method for Analysis of Nicotinic Acid/Niacin (3-pyridinecarboxylic acid), Nicotinamide, Pyridinedicarboxylic Acid, 2,5-Pyridinedicarboxylic acid, 5-Ethyl-2-methylpyridine, Ethyl nicotinate.

2,5-Pyridinedicarboxylic acid (PDA), also known as Dipicolinic acid (DPA), is a key factor in bacterial endospore heat resistance. It also plays an important role in preparing transition metal complexes for ion chromatography.

Nicotinic acid, also known as niacin, is a water-soluble B vitamin with C₆H₅NO₂ molecular formula. It is an essential nutrient that plants and animals synthesize from tryptophan. It is also used as a dietary supplement to treat pellagra, which is characterized by dermatitis of sunlight-exposed skin and is said to be caused by a corn-based diet. Nicotinic acid was found on asteroids and meteorites.

Nicotinamide, also known as niacinaminde, is a form of vitamin B₃ with the chemical formula C₆H₆N₂O₂. It is preferred treatment for pellagra and is a common treatment for acne due to it’s anti-inflammatory properties. If consumed daily, it is shown to decrease the risk of skin cancers other than melanoma. It is a derivative of Nicotinic acid and is a key component of the coenzymes nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP+).

Ethyl nicotinate, also known as nicotine acid ethyl ester, has the chemical formula C₈H₉NO₂. It is a popular topical treatment for ligament, joint, and muscle pain.

5-Ethyl-2-methylpyridine is a common precursor to Nicotinic acid with the chemical formula C₈H₁₁N. It is produced by condensation of paraldehyde and ammonia.

Nicotinic Acid/Niacin (3-pyridinecarboxylic acid), Nicotinamide, Pyridinedicarboxylic Acid, 2,5-Pyridinedicarboxylic acid, 5-Ethyl-2-methylpyridine, Ethyl nicotinate can be separated, retained, and analyzed on a Primesep 100 mixed-mode column using an analytical method with a simple gradient mobile phase of water, Acetonitrile (MeCN), and a sulfuric acid (H2SO4) buffer. This analysis method can be UV detected at 250 nm with high resolution and peak symmetry.
