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.

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).
