P-다이메틸아미노벤즈알데하이드 C화학적 특성, 용도, 생산
화학적 성질
4-Dimethylaminobenzaldehyde is white to off white crystalline powder용도
4-Dimethylaminobenzaldehyde is used to prepare colorful Schiff base adducts with amines, pyrroles and indoles. It is often used in the Ehrlich reaction, test for the presence of indoles in a sample containing alkaloids and determination of hydrazine.정의
4-Dimethylaminobenzaldehyde is a mamber of the class of benzaldehydes carrying a dimethylamino substituent at position 4. Used as an indicator for detection of indoles and hydrazine.일반 설명
Kovac′s reagent for indoles is a solution of 4-(dimethylamino)benzaldehyde and hydrochloric acid in n-butanol.Purification Methods
Crystallise DMAB from water, hexane, or from EtOH (2mL/g), after charcoal treatment, by adding excess of water. Alternatively dissolve it in aqueous acetic acid, filter, and precipitate it with ammonia. Finally recrystallise it from EtOH. It is used for the detection of pyrroles [Iyer et al.
