Acarbose EP Impurity G is a pharmaceutical grade impurity that is used as a reference standard for HPLC and LC-MS analysis. Acarbose EP Impurity G is a metabolite of acarbose and can be found in human plasma. It has been shown that Acarbose EP Impurity G induces the metabolism of glucose, which may be due to its ability to inhibit the activity of alpha-glucosidase. Acarbose EP Impurity G also inhibits the activity of pancreatic beta-cells, leading to impaired insulin secretion.

1-Phenyl-1-(pyridin-4-yl)ethanol is an analytical standard that is used in drug development. It is a metabolite of the anti-inflammatory drug, ketorolac. The purity of 1-phenyl-1-(pyridin-4-yl)ethanol is >98% and it can be custom synthesized to meet specific requirements. The 6-fluoro 3 indoxyl beta D galactopyranoside is a rifamycin that belongs to the class of antituberculosis drugs and has been shown to inhibit bacterial growth by binding to DNA dependent RNA polymerase, thereby preventing transcription and replication. Rifapentine inhibits bacterial growth by binding to DNA dependent RNA polymerase, thereby preventing transcription and replication. The high frequency of human activity has been shown using a patch clamp technique on human erythrocytes. This active form is metabolized through a number of metabolic transformations,
