Water-soluble azo compounds, a process for their preparation and their use as dyes. Water-soluble monoazo compounds of the formula (1) are described, in which D is phenylene which can be substituted by 1 or 2 substituents customary in diazo components of fiber-reactive dyes and/or by a group of the formula Y-SO2-(CHz)m- where Y has one of the meanings given below and m is the number 1 or 2, or is naphthylene which can be substituted by 1 or 2 substituents customary in diazo components of fiber-reactive dyes, or is benzothiazol-2-yl containing the group aforementioned Y-SO2-( CH2 )n- bonded to the carbocyclic ring thereof and can be substituted by a further substituent customary in fiber-reactive dyes, n is the number zero, 1 or 2, the group Y-SO2- is a fiber-reactive group from the vinylsulfonyl series, M is hydrogen or the mole equivalent of a metal, such as, in particular, an alkali metal, R1 is hydrogen, lower alkyl, phenyl or a lower alkyl which is substituted by 1 or 2 nonionic and/or anionic substituents, and R2 is lower alkyl, phenyl or a lower alkyl which is substituted by 1 or 2 nonionic and/or anionic substituents, or is phenyl which is substituted by substituents customary in fiber-reactive dyes, or is naphthyl substituted by sulfo and/or carboxy groups. Azo compounds (1) are water-soluble dyes having fiberreactive properties and dye hydroxy - and/or carboxamidocontaining material, in particular fiber material, such as wool and synthetic polyamide, and, in particular, cellulose fiber materials, such as cotton, in hues of high color strength and good fastness properties via the application and fixation processes customary for fiberreactive dyes.
