Abstract
Compounds of formula ##STR1## wherein X is long-chain alkyloxy, long-chain alkylamino or long-chain dialkylamino,
M is alkali metal, pyridinium or ammonium,
Y is hydroxy or long-chain alkyloxy,
which are especially useful in photometric and fluorimetric investigations of lipids and lipid-water interactions and of cationic biomolecules such as nicotine adenine dinucleotide.
