Chromium(III) nicotinate is an ionic substance used for chromium supplementation in some nutritional products, where it is also referred to as chromium polynicotinate.It appears in products that are referred to as a medical food used for nutritional support for conditions associated with diabetes mellitus type 2.
Picoline refers to any of three isomers of methyl pyridine (CH 3 C 5 H 4 N). They are all colorless liquids with a characteristic smell similar to that of pyridine. They are miscible with water and most organic solvents.
Methylpyridinium is prepared by treating pyridine with dimethylsulfate: [2]. C 5 H 5 N + (CH 3 O) 2 SO 2 → [C 5 H 5 NCH 3] + CH 3 OSO − 3. It is found in some coffee products. [3] It is not present in unroasted coffee beans, but is formed during roasting from its precursor chemical, trigonelline. [3]
