white to light yellow crystal powde
Used to determine the ability of an organism to split indole from the tryptophan molecule.
4-(Dimethylamino)cinnamaldehyde is a reagent used in the assay of apotryptophanase and tryptophanase. It has been used in a chromogenic method for quantifying proanthocyandines in cranberry powder.
4-(Dimethylamino)cinnamaldehyde is a reagent for assay of indole product of apotryptophanase and tryptophanase. It has been used in a chromogenic method for quantifying proanthocyandines in cranberry powder.
ChEBI: 4-dimethylaminocinnamaldehyde is a member of cinnamaldehydes.
DMACA is basically a selective staining reagent. It helps identify the flavanols by staining them blue in color.
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.
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.]
