■ KI
★ Pharmaceutical Grade KI
KI is a colorless crystal or white crystalline powder; no smell and taste salty, bitter zone. The goods is highly soluble in water, soluble in ethanol. In the humid air in a micro-deliquescence of the precipitation will be home for free iodine and yellow.
Purpose: for photographic emulsion, soap, Shiban printing, organic synthesis, pharmaceutical and chemical industries, food additives, feed additives, such as analysis of chemical reagents.
Packaging: Zhibantong, lined bag, net weight of 25 kg per barrel. Users may require special packaging.
Standard: Chinese Pharmacopoeia 2005 version 2 (pharmaceutical grade)
