Quinazoline and Quinoline Derivatives
Quinazolines and quinolines are nitrogen-containing heterocyclic compounds with aromatic structures that play a key role in the synthesis of drugs with anticancer, antimicrobial, and anti-inflammatory activity. Their derivatives feature structural modifications that optimise bioavailability and selectivity, enabling the development of new active ingredients for various therapeutic applications. These compounds are used in the manufacture of APIs for the treatment of cancer, infections, neurodegenerative diseases, and cardiovascular conditions. Additionally, quinazoline and quinoline derivatives are essential in the research of enzyme inhibitors and the design of innovative bioactive molecules.
At CymitQuimica, we offer high-purity quinazoline and quinoline derivatives for applications in chemical synthesis, pharmaceutical development, and biotechnology.

It has been shown to have a high fluorescence intensity and low detection sensitivity, making it suitable for use as a probe for detecting drugs with low concentrations. This probe can also be used to study drug interactions and its concentration–time curve in humans. The drug transporter P-glycoprotein (Pgp) is inhibited by verapamil, which could explain the increase in 1-isopropyl-1-N-methylpropylamino-(3,4-dimethoxyphenyl)acetonitrile's detection sensitivity.</p>Formula:C17H26N2O2Purity:Min. 95%Color and Shape:PowderMolecular weight:290.4 g/molBisoprolol impurity G
CAS:<p>Bisoprolol impurity G is a metabolite of bisoprolol. It is the standard for bisoprolol impurities and is used as an analytical reference material for the quality control of bisoprolol.</p>Formula:C19H33NO5Purity:Min. 95%Molecular weight:355.47 g/molN-(3-hydroxytricyclo[3.3.1.1]dec-1-yl)glycyl-L-prolinamide
CAS:<p>N-(3-hydroxytricyclo[3.3.1.1]dec-1-yl)glycyl-L-prolinamide is a metabolite that is formed when the drug product, ticagrelor, undergoes metabolism in the liver. Ticagrelor is a prodrug that requires conversion to its active form, which is N-(3-hydroxytricyclo[3.3.1.1]dec-1-yl)glycyl-L-prolinamide, before it can be used as a platelet inhibitor and antiplatelet agent for the prevention of thrombotic events such as heart attack and stroke. It has been shown to have an excellent stability profile and high purity when produced by HPLC or synthesized using the latest methodology under GMP conditions.</p>Purity:Min. 95%N1-Losartanyl-losartan
CAS:<p>N1-Losartanyl-losartan is a new nonpolar, innovative pharmaceutical agent that fulfills the needs of pharmacological research. It has been shown to be pharmacologically active in vivo and in vitro. N1-Losartanyl-losartan has been shown to be genotoxic impurities, nitrosamines, and other impurities. N1-Losartanyl-losartan is an analytical method for the determination of valsartan and its metabolites. The analytical method uses supercritical fluid chromatography with mass spectroscopy detection (SFC/MSD).</p>Formula:C44H44Cl2N12OPurity:95%NmrMolecular weight:827.81 g/mol
