Abstract
Intermediates for fluorescent dyes based on 9-carboxyethyl-6-hydroxy-3-oxo-3H-xanthene which are useful as reporters for reporter-labeled DNA fragments are described. The intermediates are protected fluorescent dyes bearing acyloxy groups at the 3 and 9 positions and an alkoxy group at the 9 position. Deprotection of the protected fluorescent dye by treatment with aqueous ammonia regenerates free dye.
