Chromium(III) picolinate (also trivalent chromium) is a chemical compound with the formula Cr(C 5 H 4 N(CO 2)) 3, commonly abbreviated as CrPic 3. It is a bright-red coordination compound derived from chromium (III) and picolinic acid .
Contact with products containing chromates can lead to allergic contact dermatitis and irritant dermatitis, resulting in ulceration of the skin—a condition sometimes called chrome ulcers. Workers that have been exposed to strong chromate solutions in electroplating, tanning, and chrome-producing manufacturers may also develop chrome ulcers.

Structure of Zn(picolinate) 2 (H 2 O) 2. Hydrogenation of picolinic acid gives piperidine-2-carboxylic acid, a precursor to the drug Mepivacaine. Picolinic acid is a bidentate chelating agent of elements such as chromium, zinc, manganese, copper, iron, and molybdenum in the human body. [5] [6] It is a substrate in the Mitsunobu reaction.
