p-Dimethylaminocinnamaldehyde (DMACA) is an aromatic hydrocarbon. It is used in an acidic solution to detect indoles.
The DMACA is any of a number of acidified DMACA solutions:
It is primarily used as a histological dye used to detect indoles, particularly for production in cells. It is used for the rapid identification of bacteria containing tryptophanase enzyme systems.[ citation needed] It is also particularly useful for localization of proanthocyanidins compounds in plants, resulting in a blue staining. It has been used for grapevine fruit [4] or for legumes foliage [5] histology.
A colorimetric assay based upon the reaction of A-rings[ clarification needed] with the chromogen. p-Dimethylaminocinnamaldehyde has been developed for flavanoids in beer that can be compared with the vanillin procedure. [6] The DMACA reagent may be superior to the vanillin procedure for the detection of catechins. [7]
The DMACA reagent changes color over several days when exposed to air but when refrigerated can be stored for up to two weeks. [8]
The DMACA reagent may also be referred to as the Renz and Loew reagent. [3] [9]
