Stability Hygroscopic
Applications Isotope labelled Drometrizole is an intermediate reactant in the synthesis of UV light absorbers for polyester fibers.

Applications Pyruvic Acid-13C3 is labelled Pyruvic acid (P998900).Pyruvic acid is an Intermediate in sugar metabolism and in enzymatic carbohydrate degradation (alcoholic fermentation) where it is converted to acetaldehyde and CO2 by carboxylase. In muscle, Pyruvic acid (derived from glycogen) is reduced to lactic acid during exertion, which is reoxidized and partially retransformed to glycogen during rest. The liver can convert Pyruvic acid to alanine by amination.
