NILE BLUE CHLORIDE Usage And Synthesis

Chemical Properties

crystalline solid

Uses

Nile Blue chloride is a histological and lipid stain.

Uses

Nile Blue A 37 is used in microscopy, immunoassays, and in laser technology. It is also suitable for the prevention of deposits during the polymerization of vinyl chloride homo-, co-, and graft polymers.

Definition

ChEBI: An organic chloride salt having 5-amino-9-(diethylamino)benzo[a]phenoxazin-7-ium as the couterion. fluorescent dye which is also a potent photosensitiser for photodynamic therapy.

Preparation

commonly known as the Nile Blue. 5-(Diethylamino)-2-nitrosophenol?and Naphthalen-1-amine hydrochloride reaction.

Biological Activity

Nile blue chloride is a green colored powder and is a member of oxazine group of dyes. It changes its color from blue (pH 9.4) to purple-red (11.0). Nile blue chloride has been used to detect DNA and lipids. In addition, it also helps to identify bacterial growth. Nile blue chloride also facilitates diagnosis of disease linked with amyloid accumulation.

Properties and Applications

bright blue. Soluble in hot water and ethanol are blue. The strong sulfuric acid for orange or brown, after dilute for blu-ray to green and then into a blue. The dye solution to join sodium hydroxide have red precipitation (precipitation soluble in ethyl ether for a green fluorescent light brown orange).
