Product Introduction
CAS No.: 122628-50-6
Main Functions
Pyrroloquinoline Quinone Disodium Salt, or PQQ as it is popularly known, is available from Yihe Biomedical at 98% purity. Our company has a registered license for this compound as per CAS No. 122628-50-6. We cater to the requirement of manufacturers who rely on raw materials with well-defined functionality, high content of the active ingredient and standard quality documentation for each batch of production when formulating food and health products.
According to Yihe Biomedical’s product listings, PQQ has been targeted towards formulations related to mitochondrial enhancement, immune system support, antioxidant defense, brain cognition enhancement and memory support, detoxification, anti-inflammatory, reproductive function promotion, cardiovascular health, liver support and activation of longevity genes. These are directions of application that make it a suitable raw material for cellular energy, cognitive nutrition, active aging as well as general health formulations.
Manufacturers can utilize this 98% assay grade to calculate formulas with precision, conduct sample comparison effortlessly, and control active ingredient level consistently. PQQ when compared to broadly mixed extracts is better suited for those customers who prefer a compact and well-defined active component. Customers are recommended to conduct product evaluation at different levels such as assay results, appearance, solubility, blending uniformity, compatibility with other nutrients, and storage stability of their own formulation before deciding for the bulk production.
Application Areas
Primarily, the scope of application for PQQ revolves around food and health product development. Exposure in the arena of nutritional supplements, it could be tested for capsules, tablets, granules, powder blends and other solid dosage or blended product formats. Similarly, for the food-related segment, the ingredient might be included in functional nutrition systems where a well-defined source ingredient is essential.
Since PQQ is frequently mixed with other bioactive nutrients, carrying out compatibility tests at the very beginning of the project cycle is a must. During the actual formulation stage, apart from achieving a good dispersion, customers should also keep their eyes on the possible color change, interaction between ingredients, content uniformity, and stability throughout processing, packaging and storage.
Ultimately, the choice of the application a source of PQQ will be finalized by the customer’s formula design, product category, target market, labeling plan, and local regulations applicable.
