Fomaldehyde (Marquis [ii] and Prochazka reagent), furfural, 4-methoxybenzalde-hyde, 4-(dimethylamino)-cinnamaldehyde and 4-(dimethylamino)-benzaldehyde (Ehrlich s, Van Urk s, Morgan-Elson or EP reagents) react according to this scheme with... [Pg.39]

Dimethylamino)-benzaldehyde — hydrochloric acid reacts less sensitively than 4-(dimethylamino)-cinnamaldehyde — hydrochloric acid in the detection of indole derivatives, but the former is better for differentiation of substances on account of the multiplicity of different color shades produced. [Pg.131]

DMCA assay is used to quantify catechins, and it is based on the formation of a green chromophore between catechin and 4-(dimethylamino)-cinnamaldehyde (DMACA) (Polster and others 2003). [Pg.66]

Dimethylamino cinnamaldehyde [6203-18-5] M 175.2, m 141 . The aldehyde crystallises from EtOH or ligroin and is dried in vacuo. The oxime has m 157° (from ligroin). The phenylhydrazone has m 169° (form MeOH). It is used as a reagent for amines (with NH3, UV has kmax at 630nm). [Konig et al.

Note The individual components of the reagent can also be applied separately one after the other [12, IS], e.g. the chromatogram is first immersed in an 8 1% methanolic 4-(dimethylamino)-benzaldehyde solution and then, after intermediate drying, sprayed with 23 % sulfuric acid [12]. 4-(Dimethylamino)-benzaldehyde can be replaced in the reagent with 4-(dimethylamino)-cinnamaldehyde [1],... [Pg.135]
