Hangzhou Yihe Biomedical Technology Co., Ltd.
Product Introduction
CAS No.: 29266-81-7
Main functions
Yihe Biomedical provides β-Nicotinamide Adenine Dinucleotide, shortened as NAD, with CAS No. 29266-81-7. It is one of biologically active compounds we have in our list, available for customers from medical, health care, and industrial sectors. Based on Yihe Biomedical’s catalog information, NAD supports several biological activities such as energy production, DNA repair, anti-aging, regulation of biological clock, and improvement of cardiovascular function.
From a developer's point of view, NAD is a great option to add to the portfolio if there is a desire for a chemically characterized coenzyme related compound rather than a plant extract that is an undefined mixture. Research and development, purchasing, and quality control workers would have no trouble recognizing the raw material due to its well-established chemical identity. At times, customers use CAS number as a tool to avoid confusions that arise from use of different English names or translation differences. Yihe Biomedical is able to provide the clients with sample testing, COA, and specification discussion before the large order turnout.
Usage sectors
The main NAD application fields are medical, health care, and industrial sectors. NAD can be the right ingredient choice for healthcare product development that emphasizes on energy metabolism, anti-aging, and support for biological rhythms. Concerning medical and industrial uses, it is the customers’ responsibility to base their product assessment on their own production standards, formula orientation, and regulatory requirements.
Being a precisely characterized functional ingredient, NAD customers should at least mention parameters such as purity standards, dosage form, packaging preferences, and documentation needs before placing an order. Sampling is certainly advisable before placing a large order in order to check for appearance, solubility, compatibility, storage behavior, and production suitability.
