Inositol Niacinate, also widely known as inositol hexanicotinate or inositol niacin ester, is a chemically defined vitamin-related compound formed by esterification of inositol with niacin, corresponding to CAS 6556-11-2. It is used as a stable vitamin B3 source in industrial nutraceutical formulation, where controlled niacin release characteristics are required at the formulation level rather than direct pharmacological action. The material is supplied for industrial use with competitive factory pricing, customized specifications, and complete documentation including MSDS, TDS, COA, supporting bulk supply.

Uses: Inositol nicotinate has the effect of lowering cholesterol and dilating peripheral blood vessels, and is used for hypercholesterolemia and atherosclerosis. It is currently used in the adjuvant treatment of hyperlipidemia, coronary heart disease, and various peripheral vascular disorders (such as arteriosclerosis obliterans, acral artery spasm, frostbite, vascular migraine, etc.).
FAQ - Technical & Supply Chain
-
Q:
In industrial liquid or solid dosage formulations, what is the primary technical advantage of using CAS 6556-11-2 over standard nicotinic acid?
A: The primary advantage lies in the metabolic "flush-free" delivery system. CAS 6556-11-2 is typically applied when a sustained-release mechanism is required. It undergoes gradual enzymatic breakdown in the body, providing a steady supply of niacin over an extended period. This makes it the preferred raw material for formulations where avoiding the acute peripheral vasodilation (skin flushing) associated with immediate-release niacin is a critical technical requirement. -
Q:
Is Inositol Niacinate used as an industrial raw material rather than a finished consumer product?
A: It is typically supplied as a raw material intended for nutraceutical and dietary supplement formulation, not as a finished retail dosage form.
