APIs for research and impurities

Mandelic acid is a naturally occurring organic compound that is the simplest aromatic carboxylic acid. It is used as an intermediate in chemical synthesis, and as a reagent in analytical chemistry. Mandelic acid can be produced synthetically by the oxidation of benzaldehyde or benzoic acid. Mandelic acid has been shown to inhibit the metabolism of many drugs, including diazepam, phenobarbital and propranolol. It also shows anti-inflammatory effects due to its ability to inhibit prostaglandin synthesis.

Rosuvastatin anhydro lactone is a pure chemical compound that is used as an analytical reference standard for high-performance liquid chromatography (HPLC) for the determination of purity and identification of impurities in pharmaceuticals. It is also utilized as a drug development, API impurity, and HPLC standard. Rosuvastatin anhydro lactone is a metabolite of rosuvastatin and is chemically designated as C22H29NO3. The CAS number for rosuvastatin anhydro lactone is 1246665-85-9.

Sterebin E is an analog of a kinase inhibitor that has shown promising anticancer activity. It is derived from a Chinese herb and has been found to induce apoptosis in human cancer cells. Sterebin E targets specific kinases involved in the cell cycle and inhibits their activity, leading to cell death. This compound has been shown to have potent inhibitory effects on various protein kinases, making it a promising candidate for the development of new cancer therapies. In addition, Sterebin E has been found in urine samples from cancer patients, suggesting that it may be a useful biomarker for tumor diagnosis and prognosis.

9-Hydroxymethyl-10-carbamoylacridan is an active metabolite of carbamazepine. It is a potent competitive inhibitor of the enzyme acetylcholinesterase, which leads to increased levels of acetylcholine in the human brain and causes decreased seizure threshold. 9-Hydroxymethyl-10-carbamoylacridan can be found in wastewater and it has been detected in the water supply and in human serum. 9-Hydroxymethyl-10-carbamoylacridan is also present in human urine and can be detected by high performance liquid chromatography (HPLC). This compound has been shown to cause epileptic seizures in humans.
