Introduction：Tetracycline is a yellow, odorless, crystalline powder. Tetracycline is stable in air but exposure to strong sunlight causes it to darken. Its potency is affected in solutions of pH below 2 and is rapidly destroyed by alkali hydroxide solutions
Appearance: Yellow,crystalline powder PH of 2% aqueous solution: 2.1 - 2.3.
Molecular formula: C22H25ClN2O8
Molecular weight: 480.9
CAS Number:64-75-5
Stability: Stable. Incompatible with strong oxidizing agents.
Solubility: H2O: 10mg/mL as a stock solution. Stock solutions should be filtered sterilized and stored at -20°C. Stable at 37°C for 4 days.
Fire Hazard: Flash point data concerning Tetracycline hydrochloride are not available, however, Tetracycline hydrochloride is probably combustible.
Application: It is a kind of pharmaceutical raw material that used for sterilization, such as pneumonia, Osteomyelitis, tympanitis, infection of biliary tract, etc.
