A new near-infrared fluorescent dye, 9-N-(2-hydroxyethyl)-N-methylamino-6-carbethoxy-SH-benzo[a]phenoxazin-5-one 1, was prepared from the reaction of N-(2-hydroxy-ethyl)-N-methyl-4-nitrosoaniline hydrochloride and ethyl 1,3-dihydroxynaphthoate. Five more fluorescent compounds were synthesized by the reaction of the resulting dye 1 with appropriate amino acid or carboxylic acids.
- Fluorescent dyes,
- benzo[a]phenoxazinone,
- fluorogenic labels
