- All the dyes studied were unpurified samples obtained from the routine manufacturing process
- A vacuum-dried sample of the quasi-crystalline form of 1 contained 4 + 2 molecules of water of hydration per molecule of 1.
- All the sodium salts of the highly sulphonated water-soluble, fibre-reactive dyes which we have studied undergo decomposition before they can melt, whether X-ray diffraction shows them to be truly crystalline, quasi-crystalline or amorphous
