Nicotinic acid and nicotinamide are both forms of vitamin B3, also known as niacin. They play crucial roles in the body’s energy metabolism and are essential for maintaining the health of the skin, nervous system, and digestive system.
- Nicotinic Acid (Niacin): This is one of the two principal forms of vitamin B3. Nicotinic acid is commonly used as a dietary supplement to treat vitamin B3 deficiency, and it’s also prescribed in higher doses to help lower cholesterol levels. It works by dilating blood vessels, which can lead to a flushing sensation, hence it is sometimes referred to as “flushing niacin.”
- Nicotinamide: Also known as niacinamide, this is the other principal form of vitamin B3. Nicotinamide is a precursor to nicotinamide adenine dinucleotide (NAD+), a coenzyme involved in various cellular processes, including energy metabolism. Nicotinamide is often used in skincare products for its anti-inflammatory properties and its ability to improve the appearance of aging skin and reduce hyperpigmentation.
Tranexamic acid, on the other hand, is a synthetic derivative of the amino acid lysine. It is primarily used as an antifibrinolytic agent, meaning it helps to prevent the breakdown of blood clots. Tranexamic acid is commonly used to treat or prevent excessive bleeding, particularly in conditions such as heavy menstrual bleeding, traumatic hemorrhage, and during surgeries where significant blood loss is expected. Additionally, it has been investigated for its potential role in treating melasma, a common skin condition characterized by hyperpigmentation.
Each of these compounds has distinct biochemical properties and medical applications, but they all play important roles in human health and medicine.
Nicotinic Acid, Nicotinamide, Tranexamic Acid can be retained and separated using a Primesep 100 mixed-mode stationary phase column. The analysis employs an isocratic method with a simple mobile phase comprising water, acetonitrile (MeCN), and sulfuric acid as a buffer. This method allows for detection using UV at 210 nm

HPLC Method for Simultaneous Determination of Nicotinic Acid, Nicotinamide, Pyridine Dicarboxylic Acid, Ethyl Methyl Pyridine and Ethyl Nicotinate on Primesep 100 Column
August 29, 2022
Separation type: Liquid Chromatography Mixed-mode
High Performance Liquid Chromatography (HPLC) Method for Analysis of Nicotinic Acid, Nicotinamide, Pyridine Dicarboxylic Acid, Ethyl Methyl Pyridine and Ethyl Nicotinate Nicotinic acid, also known as Niacin or Vitamin B3, is an essential nutrient that plants and animals synthesize from tryptophan. It is also used as a dietary supplement to treat pellagra. A derivative of Nicotinic acid, Nictotinamide, is a key component of the coenzymes nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP+). Pyridine Dicarboxylic acid (PDA), or 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. Ethyl Methyl Pyridine is a common precursor to Nicotinic acid. Ethyl nicotinate, or nicotine acid ethyl ester, is a popular topical treatment for ligament, joint, and muscle pain. These 5 organic compounds 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.

Analysis of Nicotinic Acid and Nicotinamide (Vitamin B3) on Newcrom AH Column
July 6, 2015
Nicotinamide is the amide form of nicotinic acid. Nicotinic acid is in the vitamin B group and is converted to nicotinamide in vivo. Newcrom AH was used to separate nicotinamide and nicotinic acid. Newcrom AH separates acids using ion-exclusion, retains basic compounds by cation-exchange, and neutral compounds by reverse-phase mechanism.

Separation of Nicotinamide and Related Substances
May 11, 2015
A complex mixture of nicotinamide and related impurities was separated on Obelisc R mixed-mode column. Nicotinamide, methylnicotinamide, nicotinamide adenine mononucleotide, nicotinamide adenine dinucleotide, and adenosine monophosphate were baseline resolved in a 15 minute long method. This mixed-mode approach can be used for analysis of other nucleotides. Obelisc R trimodal column separates this complex mixture based on reversed-phase, cation-exchange and anion-exchange mechanisms. Retention is controlled by amount of ACN, buffer concentration and buffer pH. Additional selectivity can be gained by exploring various buffers within the same pH
Application Column
Obelisc R
SIELC has developed the Obelisc™ columns, which are mixed-mode and utilize Liquid Separation Cell technology (LiSC™). These cost-effective columns are the first of their kind to be commercially available and can replace multiple HPLC columns, including reversed-phase (RP), AQ-type reversed-phase, polar-embedded group RP columns, normal-phase, cation-exchange, anion-exchange, ion-exclusion, and HILIC (Hydrophilic Interaction Liquid Chromatography) columns. By controlling just three orthogonal method parameters - buffer concentration, buffer pH, and organic modifier concentration - users can adjust the column properties with pinpoint precision to separate complex mixtures.
