1-Methylnicotinamide chloride

(1005-24-9)
Nicotinamide is a precursor of NAD and NADP , which serve essential functions in modulating cellular redox status and controlling signaling and transcriptional events. 1-Methylnicotinamide (MNA) is a primary metabolite of nicotinamide produced by the action of nicotinamide N-methyltransferase (NNMT; ). It demonstrates antithrombotic and anti-inflammatory properties through direct action on the endothelium by a mechanism involving the prostacyclin pathway and by improving nitric oxide bioavailabi

In the analysis work, it is often necessary to use a compound of good quality and accurate content, which is used as a comparison for detection control, or used to calibrate the instrument. This compound is called a standard. Or standard. The standard product refers to the standard substance used to determine the potency of biological products. The production department must provide the standard product expressed in units (μ) of its potency when it is approved as a quality standard for biological products. According to the application, the standard products for inspection can be divided into biological standard products for biological verification of biological products, endocrine drugs, antibiotics and so on.
