What are the applications of Application

9-Maleimidoacridine is a thiol-reactive fluorescent reagent

Purification Methods

Purify NAM by chromatography on silica gel using CH2Cl2 as eluant. Evaporation of pooled fractions that gave the correct NMR spectra gave a solid which was crystallised from Me2CO as pale yellow prisms. IR max (nujol): 1710 (imide); UV (MeOH): max (nm), ( 1cm-1): 251 (159 500), 343 shoulder (7 700), 360 (12 400) and 382shoulder (47 000). [Mashida et al.
