Any of three isomeric compounds, C7H9N, used to make dyes.


(tɒˈljuːɪˌdiːn) or


(Elements & Compounds) an amine derived from toluene existing in three isomeric forms; aminotoluene. The ortho- and meta- isomers are liquids and the para- isomer is a crystalline solid. All three are used in making dyes. Formula: C6H4CH3NH2
[C19: from tolu(ene) + -ide + -ine2]

As shown in Table-1, the retention and resolution of the phenylamine, 4-methylaniline and 3,5-dimethylaniline derivatives of hydantoin-5-acetic acid on the CHI-DMB column were approximate agreement, and the phenylamine derivative of hydantoin-5-acetic acid would be chosen as a typical sample.
1: the 3-nitroaniline derivative of hydantoin-5-acetic acid, 2: the phenylamine derivative of hydantoin-5-acetic acid, 3: the 4-methylaniline derivative of hydantoin-5-acetic acid, 4: the 3,5-dimethylaniline derivative of hydantoin-5-acetic acid; mobile phase composition on the CHI-DMB column: n-hexane 80%; mobile phase composition on the Chiralcel OD-H column: n-hexane 85%; t 1 : retention time of the first enantiomer; t 2 : retention time of the second enantiomer; Alpha: separation factor; R s : resolution; flow rate: 1.
