The following standards of dyes, used in the pharmaceutical and food industry, are listed with common description, E code and color index number (C.I.) for an easy assignment.
The Commission on Pharmaceutical Enzymes was formed in 1960, with a remit to establish quantitative methods and an exact definition of enzyme activity for pharmacological significant enzymes. One consequence of the work of FIP (Federation International Pharmaceutique) has been the production and certification of reference substances for both enzymes and substrates. More recently the work of the Commission has been reflected in those monographs of the European Pharmacopoeia which call for enzyme standards. The FIP products marked (EP) in this list are those which are required in certain EP monographs.
10 liquid CRMs, certified by the Physical Chemical Division of the Central Office of Measures (GUM), Warsaw, Poland, covers the wide range of refractive index from 1.333 (water) to 1.657 (1-bromonaphthalene).
