Abstract
This invention relates to fluorescent 7-hydroxy coumarin compounds with substitutions in the 4 position having a length greater than one carbon atom. The compounds thus are related to 4-methylumbelliferone (7-hydroxy-4-methyl coumarin, or 4-MU), the detectable label used in the IM.sub.x .RTM. instrument assays (Abbott Laboratories, Abbott Park, Ill.). The substitutions in the 4 position are branched and include functional groups for coupling to biological molecules.
