CAS:Trans-4-(aminomethyl)cyclohexanecarboxylic acid (AMCA) is a histamine antagonist that is used to treat bowel disease. It may also be useful for the treatment of other inflammatory diseases and as an anticoagulant. AMCA has been shown to be safe and effective for the prevention of postoperative bleeding in patients who are undergoing major surgery. This drug is a potent inhibitor of platelet aggregation, but does not affect the function of erythrocytes or leukocytes. AMCA inhibits platelet aggregation by blocking the binding of adenosine diphosphate (ADP) to its receptor on platelets, thus inhibiting ADP-mediated activation of phospholipase A2 and arachidonic acid release from membranes. An increase in blood levels of AMCA may lead to cardiac toxicity and bleeding events.Fórmula:C8H15NO2Pureza:Min. 95%Peso molecular:157.21 g/molIsotretinoin-d5 (Tretinoin EP Impurity A-d5, 13-cis-Retinoic Acid-d5)

CAS:Ambroxol hydrochloride impurity D is a diammonium salt with the molecular formula (C6H14N2)2NH4. It has a detection time of 2 minutes and a sensitivity of 0.1 ppm. Chromatographic detection can be used to screen for this impurity in valsartan, which is a drug used to treat high blood pressure. The chromatographic method uses a liquid column with a UV-detection wavelength of 210 nm and an injection volume of 10 μL. The detection method is based on the headspace technique, which involves collecting volatile components from the sample headspace using gas chromatography with flame ionization detection. The hydrogen phosphate ions in the sample react with phosphoric acid to produce hydrogen phosphate and water vapors, which are then measured as an indication of impurities.Pureza:Min. 95%Ethyl 2-cyano-4-methylpent-2-enoate
