Description

Pyrroloquinoline quinone (CAS 72909-34-3 ), commonly known as PQQ or coenzyme PQQ, is a redox-active cofactor found naturally in trace amounts in certain foods and in human breast milk. In commercial applications, it functions as an antioxidant and cellular energy-support ingredient, primarily targeting the dietary supplement and functional food markets across the global industry. PQQ is most prominently used in nutraceutical formulations such as capsules, tablets, and softgels, where it is positioned around mitochondrial health and cognitive support for consumers. In functional food and beverage development, it is incorporated at low inclusion levels to deliver antioxidant activity without affecting the organoleptic properties of the final product. Agricultural and feed researchers have evaluated PQQ for its role in supporting microbial activity and plant growth promotion, particularly in specialized biostimulant formulations for crops. Biotechnology and life science applications include use as a research reagent and enzyme cofactor in cell biology studies, requiring high precision and consistent material performance. PQQ is commercially supplied as a fine crystalline powder, typically as the disodium salt form, which offers improved solubility for complex formulation work and manufacturing processes. Standard grades include food-grade and supplement-grade material meeting specifications relevant to dietary ingredient regulations. Purity levels of 98% and above are standard for applications.
