Synthetic Dyes in Biology, Medicine and Chemistry is a guide in selecting dyes for special purposes in biology, medicine, chemistry, and other related fields. It aims to help professionals including histologists, cytologists, and other biology and medicine experts, such as chemists and general scientists. The dyes discussed in this book are categorized in 17 different classes according to the nature of their salt-forming sidechains, the colligators. This book also presents the uses of each dye. The spectral curve, which is the ionic and/or molecular weight of each dye, is also covered in this book. Likewise, this text provides the structural and empirical formulae of the spectral curve. Part I tackles various groups of dyes. These groups are the non-ionic, anionic, and cationic dyes. The anionic dyes are further grouped as wholly acid, weakly amphoteric, and moderately or strongly amphoteric. The subsequent part deals with the examples of dyes that do not fit the categories mentioned in Part I. These miscellaneous dyes are vat, reactive, disperse, and ingrain dyes. Part III presents the dyes in different tables according to wavelength of maximum absorption and ionic or molecular weight. This book also covers the stabilized diazonium salts and substituted napthols.
