Acid Blue 90 , its cas register number is 6104-58-1. It also can be called Coomassie ; Coomassie Brilliant Dyes ; C.I. 42655 ; N-[4-[[4-[(4-Ethoxyphenyl)amino]phenyl][4-[ethyl[(3-sulfophenyl)methyl]amino]-2-methylphenyl]methylene]-3-methyl-2,5-cyclohexadien-1-ylidene]-N-ethyl-3-sulfobenzenemethanaminium inner salt monosodium salt ; and Coomassie Brilliant Blue G-250 . It may be added to undenatured protein in PAGE in place of SDS in a technique called BN-PAGE; both SDS and CBB have the effect of imparting a net negative charge upon the proteins. It is hazardous, so the first aid measures and others should be known. Such as: When on the skin: first, should flush skin with plenty of water immediately for at least 15 minutes while removing contaminated clothing. Secondly, get medical aid. Or in the eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Then get medical aid soon. While, it's inhaled: Remove from exposure and move to fresh air immediately. Give artificial respiration while not breathing. When breathing is difficult, give oxygen. And as soon as to get medical aid. Then you have the ingesting of the product: Wash mouth out with water, and get medical aid immediately. Notes to physician: Treat supportively and symptomatically.
In addition, Acid Blue 90 (CAS NO.6104-58-1) could be stable under normal temperatures and pressures. It is not compatible with strong oxidizing agents, and you must not take it with incompatible materials. And also prevent it to broken down into hazardous decomposition products: Nitrogen oxides, carbon monoxide, oxides of sulfur, carbon dioxide, nitrogen.
