Product Name:Spectinomycin dihydrochloride pentahydrate
English Name:Spectinomycin dihydrochloride pentahydrate
CAS No.:22189-32-8
Aliases:Actinospectacin dihydrochloride pentahydrate, Spectinomycin hydrochloride pentahydrate
Molecular Formula:C14H24N2O7·2HCl·5H2O
Physical Properties:Molecular weight: 495.31. White or off-white crystalline powder with a bitter taste. Freely soluble in water, slightly soluble in methanol, practically insoluble in ethanol, ether and chloroform. Hygroscopic. Relatively stable in acidic to neutral aqueous solutions; decomposes under strongly alkaline conditions.
Uses:This is an aminocyclitol antibiotic primarily used for the treatment of gonococcal infections and urogenital tract infections caused by Neisseria gonorrhoeae. It is also used in veterinary medicine for mycoplasmosis, colibacillosis and other bacterial infections in poultry and livestock. In biochemical and pharmacological research, it is used as an antibiotic reference standard.
Technical Specifications:
White or off-white crystalline powder.
Assay (on dried basis) ≥98.0%.
Specific rotation [α]D20 = +15° to +21° (c=1, H2O).
Water content (Karl Fischer): 15.0%-20.0%.
Residue on ignition ≤0.1%.
