Yellow Solid

Used for fluorometric determination of sulfites in foods and fermentation products.

Reagent used for the fluorescent labeling of thiols, sulfides and sulfites for determination by HPLC

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. Chem Pharm Bull Jpn 26 596 1978, Schuldiner et al. Eur J Biochem 25 64 1972,]
