Definition

ChEBI: 4-dimethylaminocinnamaldehyde is a member of cinnamaldehydes.

General Description

DMACA is basically a selective staining reagent. It helps identify the flavanols by staining them blue in color.

Biochem/physiol Actions

Reagent for assay of indole product of apotryptophanase and tryptophanase. DMAC produces colored adducts with flavanols for subsequent HPLC. It has been used in a chromogenic method for quantifying proanthocyandines in cranberry powder.

Purification Methods

The aldehyde crystallises from EtOH or ligroin and is dried in vacuo. The oxime has m 157o (from ligroin). The phenylhydrazone has m 169o (form MeOH). It is used as a reagent for amines (with NH3, UV has max at 630nm). [K.nig et al. Chem Ber 61 2075 2075, Quareshi & Kahn Anal Chim Acta 86 309 1976, Beilstein 14 III 184, 14 IV 197.]
