It is indicated as ajunctive therapy. It can be found in various foods、such as liver、chicken、beef、cereal、peanuts and legumes. Niacin is also used as a pharmaceutical to reverse atherosclerosis. (A729)、Use Classification: Cosmetics -> Smoothing、Antistatic、Industry Uses: Flavoring and nutrient、Intermediate、Consumer Uses: Flavoring and nutrient、Household Products: Information on 1 consumer products that contain Niacin in the following categories is provided:、• Personal Care、Methods of Manufacturing: In an aqueous solution 5-ethyl-2-methylpyridine is oxidized to nicotinic acid in a single-tube reactor by using an excess of nitric acid. The continuous process takes place at 230-270 °C and 6-8 MPa. Pyridine-2、5-dicarboxylic acid is formed as an intermediate、but is not stable under the reaction conditions、undergoing decarboxylation to nicotinic acid nitrate. Neutralization of the nitrate with 5-ethyl-2-methylpyridine yields nicotinic acid. Water and carbon dioxide formed in the reaction are separated from the product. The nitrogen oxide formed is oxidized with air to nitrogen dioxide and then absorbed in water to yield nitric acid、which is recycled into the process.、Preparation by oxidation of alkyl beta-substituted pyridines、Preparation by oxidation of nicotine、Commercial sources: Synthetic nicotinic acid is made by oxidation of nicotine、quinoline、or 2-methyl-5-ethylpyridine (from ammonia and formaldehyde or acetaldehyde).、Formulations、Preparations: Table: Niacin Preparations [Table#4463]、Table: Niacin Combination Preparations [Table#4464]、Table: Niacin Preparations [Table#4465]、Grades: National Formulary、Food Chemical Codex、blended with soy flour (animal feeds)、Niacin is commercially available as conventional (immediate-release) and extended-release preparations and in fixed combination with lovastatin. Niacin also is available as a dietary supplement、these preparations are not FDA-labeled for management of dyslipidemias and should not be used as substitutes for prescription-only niacin preparations.、U.S. Production: 2023: 235、012 lb、2022: 334、132 lb、2021: 710、858 lb、2020: 396、391 lb、(1972) 2.49X10+9 GRAMS、NIACIN & NICOTINAMIDE、(1975) 2.5X10+9 GRAMS、Non-confidential 2016 Chemical Data Reporting (CDR) information on the production and use of chemicals manufactured or imported into the United States.
