Acetone, FCC also known as 2-propanone, is an organic compound and a colorless, flammable liquid. Due to its miscibility with water, it serves as an important solvent. The U.S. Food and Drug Administration (FDA) has determined acetone is safe for use as an indirect food additive in adhesives and food-contact coatings and is regarded as a Generally Recognized as Safe (GRAS) substance at certain concentrations. Spectrum Chemical offers over 300 Food Grade (FCC) chemical ingredients packaged in laboratory size bottles to production drum quantities and are manufactured, packaged and stored under current Good Manufacturing Practices (cGMP) per 21CFR part 211 in FDA registered and inspected facilities.

T-CAL® Turbidity Standards are stable Formazin standards prepared in ready-to-use concentrations to ensure accurate turbidity measurements. All concentrations are verified to meet tight quality control specifications, are EPA & ISO compliant for reporting (1 per EA )

Starch, Soluble, Powder, Reagent, ACS is indicator for redox titrations where triiodide is present. Starch forms a very dark blue-black complex with triiodide which can be made by mixing iodine with iodide (often from potassium iodide). The color of the starch complex is so deep, that it can be detected visually when the concentration of the iodine is as low as 0.00002 M at 20 °C. As an ACS grade quality reagent, its chemical specifications are the de facto standards for chemicals used in many high-purity applications and typically designate the highest quality chemical available for laboratory use. Spectrum Chemical manufactured Reagent ACS grade products meet the toughest regulatory standards for quality and purity.
