溶于水，水溶液为蓝红色，硫酸介质中为棕色。 玫瑰红是一种红色或玫瑰色染料，是阴离子性质。它是荧光素的4、5、6、7-四氯2′，4′，5′，7′-四碘衍生物。在干眼症、疱疹性角膜炎等眼表疾病中，它广泛用于眼表上皮细胞的损伤检测。玫瑰红具有温和的抗病毒效力 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.
