Field desorption mass spectral analysis of some nonmutagenic benzidine-based pigments

This paper is concerned with field desorption mass spectral (FDMS) analysis of novel disazomethine, disazoacetoacetanilide (diarylide) and disazopyrazolone pigments containing nonmutagenic benzidine homologs. The FD spectra of the aforementioned types of pigments are characterized by intense parent...

Description
Summary:This paper is concerned with field desorption mass spectral (FDMS) analysis of novel disazomethine, disazoacetoacetanilide (diarylide) and disazopyrazolone pigments containing nonmutagenic benzidine homologs. The FD spectra of the aforementioned types of pigments are characterized by intense parent ion peaks [M +.] and relatively intense [M +]/2 daughter ions, a pattern which serves as a fingerprint for these molecular structures.
