Descripción general

Product Description：
Rose Bengal is a stain used in the eye drops to identify the eye damage. It finds application in the preparation of foraminifera for microscopic analysis, photosensitizing reactions and as a dye. In synthetic chemistry, it is utilized to convert triplet oxygen to singlet oxygen, which is used in [2+2] cycloadditions with alkenes. Its derivatives have important medical functions and used for the treatment of cancer. It acts as an alternative to phloxine B in Kreyberg's stain for keratin and mucus. As a fluorescent probe, it is used for the determination of NAD binding sites of alcohol dehydrogenase. Product Application：
Rose Bengal is a red or rose color dye and is anionic in nature. It is a 4,5,6,7-tetrachloro 2′,4′,5′,7′-tetraiodo derivative of fluorescein. It is widely used to detect damage to the ocular surface epithelium in ocular surface diseases such as dry eye and herpetic keratitis. Rose Bengal has mild antiviral potency.Rose Bengal is used to stain dead and degenerating cells and mucus.
