The Cellulose microcrystalline, with the CAS registry number 9004-34-6, is also known as alpha-Cellulose. It belongs to the product categories of Cellulose;Materials Science;Natural Polymers;Polymer Science;Polymers.This chemical's molecular formula is (C6H10O5)n. Its EINECS number is 232-674-9. What's more,Its systematic name is 1H-Benzimidazole-7-carboxylic acid, 2-ethoxy-1-((2'-(1H-tetrazol-5-yl)(1,1'-biphenyl)-4-yl)methyl)-.It is a polysaccharide with glucose units linked as in CELLOBIOSE. It is the chief constituent of plant fibers, cotton being the purest natural form of the substance. As a raw material, it forms the basis for many derivatives used in chromatography, ion exchange materials, explosives manufacturing, and pharmaceutical preparations.
Cellulose microcrystalline is combustible. Incompatible with strong oxidizing agents including bromine pentafluoride, sodium nitrate, fluorine, perchlorates, perchloric acid, sodium chlorate, magnesium perchlorate, F2, zinc permanganate, sodium nitrite, sodium nitrate, sodium peroxide. Nitration with a mixture of nitric and sulfuric acids produces Cellulose microcrystalline nitrates (celluloid pyroxylin, soluble pyroxyline, guncotton) which are flammable or explosive.The Cellulose microcrystalline is hamfull to the health. It is irritating to the respiratory system.When you use it ,avoid contact with skin and eyes.
Uses of Cellulose microcrystalline: It is high purity cellulose powders for partition chromatography.
