Chromium picolinate is an organometallic compound. The following is a description of its properties, uses, preparation and safety information: Properties: APPEARANCE: Chromium picolinate is a brown solid. SOLUBILITY: Chromium picolinate is soluble in some organic solvents such as dimethylformamide (DMF) and dichloromethane (DCM). STABILITY: Chromium picolinate is stable to air and humidity, but contact with strong oxidizing agents should be avoided. Uses: CATALYST: Chromium Pyridine Carboxylate is used as a catalyst in organic synthesis, especially in oxo-cyclization reactions. Dye: It can also be used as a raw material for organic dyes. Method of Preparation: Preparation of chromium picolinate is usually obtained by reacting the oxidative addition of chromium benzoate (Cr(OOCPh)3) and pyridine. The reaction can be carried out in a suitable solvent and at a suitable temperature. Safety Information: Chromium picolinate may be irritating to the eyes and skin and appropriate protective equipment should be worn when handling it. It should be stored in a dry, well-ventilated area away from sources of ignition and strong oxidizing agents. Avoid generating dust when using or handling to avoid inhalation or ingestion. Follow laboratory safety procedures when handling and working with chromium picolinate.
