General description

Mettler-Toledo calibration substance ME 51143091, saccharin is an analytical standard, designed for the routine calibration of Mettler-Toledo melting point instrument. Its value is an average of 6 to 12 measurements with a Mettler-Toledo MP70 Excellence instrument that is calibrated against primary standards. The melting point is validated by Capillary method as per European Pharmacopeia (2.2.14.)


Saccharin Mettler-Toledo calibration substance ME 51143091 is a melting point calibration standard used to calibrate Mettler-Toledo mp instruments.

Biochem/physiol Actions

A sweet tastant for mammals. A glycerol taste receptor binding site specific for glucose has been proposed in drosophila.

Cocrystals constitute an important class of pharmaceutical solids for their remarkable ability to modulate solubility and pH dependence of water insoluble drugs. Here we show how cocrystals of indomethacin-saccharin (IND-SAC) and carbamazepine-saccharin (CBZ-SAC) enhance solubility and impart a pH-sensitivity different...
