The reaction of disodium cromoglycale with five cationic dyes: crystal violet, Janus green, methylene blue, methyl green, and safranine, was investigated. Spectroscopic shifts indicated that at low concentration (0.01 m M ) all these dyes were able to form complexes (ion paris) with the cromoglycale anion. In addition, the complexes formed by crystal violet and Janus green were extractable into chloroform.
