Piperacilloic acid is a synthetic compound that exhibits antibacterial activity. It has been shown to be effective against human pathogens, including urothelial carcinoma and human serum. Piperacilloic acid binds to the amino acids lysine and arginine in bacterial proteins and inhibits protein synthesis by inhibiting the function of enzymes that require these amino acids for their activity. The potency of piperacillin is low, but it is activated by hydrolysis in the acidic environment of the stomach or intestinal tract. Piperacilloic acid also has potential as a contraceptive agent because it may inhibit transcriptional regulation of genes that are involved in sperm production.

N-Desacetyl thiocolchicoside is a white crystalline powder that is soluble in water, methanol and acetone. It has a molecular weight of 320.2 and an empirical formula of C6H14O5. N-Desacetyl thiocolchicoside is used as an analytical standard for HPLC analysis, as a Research and Development (R&D) material for drug development, and as an impurity standard for the manufacture of pharmaceutical products. This compound has been shown to be a metabolite of thiocolchicoside and structurally similar to the drug product chitinase.

Etofenamate impurity

Semaglutide impurity.

Chlorthalidone impurity E is an analytical standard for the HPLC analysis of chlorthalidone in pharmaceutical drug products and is a metabolite of chlorthalidone. Chlorthalidone impurity E is an API impurity that can be found in the synthesis of chlorthalidone, and it has been detected as a minor component in certain drug products. It is important to have an accurate specification for this compound, since it can affect the pharmacological properties of the drug product. The purity level of this compound must be at least 98% or greater to ensure that there are no contaminants present. This compound is also a metabolite of chlorthalidone and is used as a pharmacopoeia reference substance for testing equipment calibration.END>
