2-Methoxy-5-methylaniline

2-???-5-????? C??? ??, ??, ??

??? ??

brown to black crystalline chunks

??

2-Methoxy-5-methylaniline was used in the synthesis of 4-(4-Amino-5-methoxy-2-methylphenylazo)-5-hydroxy-naphthalene-2,7-disulfonic acid. 2-Methoxy-5-methylaniline was used to analyse the application of polymeric ionic liquids as selective solid-phase microextraction sorbent coatings for the analysis of genotoxic impurities and structurally alerting compounds such as alkyl halides and aromatics. 2-Methoxy-5-methylaniline was used in a study to develop a sensitive analytical method for the determination of aromatic amines found in commercial hair dyes using high liquid chromatography coupled to an electrochemical detector by using the ionic liquid 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide in the mobile phase.

?? ??

White to silver-gray odorless crystals.

??? ?? ??

Insoluble in water.

?? ???

2-Methoxy-5-methylaniline is sensitive to moisture and temperatures greater than 104°F. Incompatible with strong oxidizing agents .

???

A possible carcinogen.

????

2-Methoxy-5-methylaniline is nonflammable.

Safety Profile

Confirmed carcinogen with experimental carcinogenic and neoplastigenic data. Moderately toxic by ingestion. A skin and eye irritant. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx. See also ESTERS.

??? ??

p-Cresidine is used as an intermediate in the production of various azodyes, printing inks, and pigments; including 11 dyes that are produced commercially in the United States. Human exposure to p-Cresidine occurs primarily through inhalation of

Carcinogenicity

p-Cresidine is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.

UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required

? ???

Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides.
