Sulphonamide-amino esters

These unexacting requirements make the simplest unsulphonated azo structures, often monoazo types, quite acceptable [80]. Typical of the least polar members of this class are Cl Solvent Yellow 2 (4-68), Cl Solvent Orange 1 (4.69) and Cl Solvent Red 17 (4.70). Simple azo structures carrying sulphonamide, sulphone or carboxylate ester groups are used where a somewhat more polar, less soluble dye is needed. Simple disazo compounds (4-amino-azobenzene— 2-naphthol, for example) are used as red solvent dyes. Probably the only structural feature worthy of note in this class is the occasional adoption of structures carrying long alkyl chains to enhance solubility, as in the case of the disazo dye Cl Solvent Yellow 107 (4.71).

Dis-Cl is in some respect similar to Dns-O. It reacts with primary and secondary amines, amino adds, imidazoles, phenols and even with alcohols to form the corresponding amides or esters (171). The sulphonamides are stable to hydrolytic cleavage with 6 M HCL Dis-Q is therefore a suitable reagent for the determination of... 

In general, the more polar the plasticizer the greater its impact on the polymer and compounds featuring phosphate, sulphonamide, chlorosulphonate, chloro, amino and ester groups are commonly effective.
