Pyrroloquinolinequinone disodium salt

Pyrroloquinolinequinone disodium salt (CAS 122628-50-6), commonly known as PQQ, is the water-soluble sodium salt form of methoxatin used in nutritional and pharmaceutical applications. It functions as a redox-active cofactor and antioxidant ingredient, supporting mitochondrial health claims in finished supplement formulations. PQQ is primarily used in dietary supplements such as capsules, tablets, and softgels.

In these applications, it is positioned around cognitive function and cellular energy support. In functional food and beverage formulations, it is incorporated as an active nutrient ingredient at low inclusion levels. Pharmaceutical manufacturers use it as an active or supporting ingredient in nutraceutical-grade preparations targeting oxidative stress pathways. In animal nutrition, it is evaluated as a feed additive for livestock.

This material supports antioxidant status in both livestock and companion animal products. Pyrroloquinolinequinone disodium salt is supplied as a fine crystalline powder, typically in orange to dark red coloration. Standard commercial grades include food-grade and supplement-grade specifications. Material is commonly tested against purity benchmarks of 98% or higher by HPLC to ensure high quality for industrial use.

Packaging is available in small research quantities through to kilogram-scale lots for commercial production runs. This ensures flexibility for both pilot studies and large-scale manufacturing requirements.
