Pure & USP Grade
Chromium (III) picolinate (CrPic3) is a pinkish-red compound sold as a nutritional supplement to treat type 2 diabetes and promote weight loss. Small quantities of chromium are needed for glucose utilization by insulin in normal health, but deficiency is extremely rare and has only been observed in hospital patients on long-term defined diets.
Chromium Picolinate USP Grade
C18H12N3O6Cr -- 418.31
Chromium Picolinate contains not less than 98.0 percent and not more than 102.0 percent of C18H12N3O6Cr, calculated on the dried basis.
Packaging and storage: Preserve in tight containers.
A: Infrared Absorption.
B: To 5 mL of a solution (1 in 250) in a test tube add 1 mL of 5 N sodium hydroxide and 10 drops of 30% hydrogen peroxide, and heat gently for about 2 minutes: a yellow color develops.
Loss on drying: Dry it at 105C for 4 hours: it loses not more than 4.0% of its weight.
Chloride: Dissolve 30 mg of Chromium Picolinate in 30 to 40 mL of water, and heat to 70C. Cool overnight, and filter to remove the precipitate. Add 1 mL each of nitric acid and silver nitrate TS, and add sufficient water to make 50 mL. Mix, and allow to stand for 5 minutes, protected from direct sunlight: any turbidity formed is not greater than that produced in a similarly treated control solution containing 0.25 mL of 0.002 N hydrochloric acid (0.06%).
Sulfate: Dissolve 100 mg of Chromium Picolinate in 30 to 40 mL of water, and heat to 90C. Cool overnight, and filter to remove the precipitate. Add 1 mL of 3 N hydrochloric acid, 3 mL of barium chloride, and sufficient water to make 50 mL. Mix, and allow to stand for 10 minutes: any turbidity formed is not greater than that produced in a similarly treated control solution containing 0.2 mL of 0.02 N sulfuric acid (0.2%).
Standard stock solution: Transfer about 0.283 g of potassium dichromate, previously dried at 120C for 4 hours and accurately weighed, to a 1000-mL volumetric flask, dissolve in and dilute with water to volume to obtain a solution having a known concentration of about 100 µg of chromium per mL, and mix. Store in a polyethylene bottle.
Standard preparations: Separately transfer 1.0 mL and 2.0 mL of the Standard stock solution to 100-mL volumetric flasks, and transfer 1.5 mL and 2.0 mL of the Standard stock solution to separate 50-mL volumetric flasks. Add 1.0 mL of nitric acid to each flask, dilute the contents of each flask with water to volume, and mix. These Standard preparations contain 1.0, 2.0, 3.0, and 4.0 µg of chromium per mL, respectively.
Assay preparation: Transfer about 200 mg of Chromium Picolinate, accurately weighed, to a 500-mL volumetric flask, and add 25 mL of water. Slowly add 10 mL of nitric acid, and boil for 10 minutes with constant swirling. Cool the solution, dilute with water to volume, and mix. Filter a portion of the solution, and transfer 5 mL of the filtrate to a 100-mL volumetric flask. Add 1 mL of nitric acid, dilute with water to volume, and mix.
Procedure: Concomitantly determine the absorbances of the Standard preparations and the Assay preparation at the chromium emission wavelength of 357.9 nm, with a suitable atomic absorption spectrophotometer equipped with a chromium hollow-cathode lamp and an air–acetylene flame, using diluted nitric acid as the blank. Plot the absorbances of the Standard preparations versus chromium concentration, in µg per mL, and draw the straight line best fitting the four plotted points. From the graph so obtained, determine the chromium concentration, in µg per mL, in the Assay preparation. Calculate the quantity, in mg, of C18H12N3O6Cr in the portion of Chromium Picolinate taken by the formula:
(418.31 / 51.996)(10C)
in which C is the concentration, in µg per mL, of chromium in the Assay preparation; 418.31 is the molecular weight of chromium picolinate; and 51.996 is the atomic weight of chromium.

Fire Extinguishing Media: Water spray, dry chemical, alcohol foam, or carbon dioxide.
Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full face piece operated in the pressure demand or other positive pressure mode.
6. Accidental Release Measures
Small Spill: Use appropriate tools to put the spilled solid in a convenient waste disposal container.
Large Spill: Corrosive solid. Stop leak if without risk. Do not touch spilled material. Use water spray to reduce vapors. Prevent entry into sewers, basements or confined areas; dike if needed. Eliminate all ignition sources.
7. Handling and Storage
Keep Chromium Picolinate in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Isolate from incompatible substances. Containers of Chromium Picolinate may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product. Avoid dust formation.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits: None established.
Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures as low as possible. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved): For conditions of use where exposure to dust or mist is apparent and engineering controls are not feasible, a particulate respirator (NIOSH type N95 or better filters) may be worn. If oil particles (e.g. lubricants, cutting fluids, glycerin, etc.) are present, use a NIOSH type R or P filter. For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.
Skin Protection: Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact.
Eye Protection: Use chemical safety goggles and/or full face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area.
