Dihydro Montelukast

Dihydro montelukast is a potential impurity found in commercial montelukast preparations. Montelukast (sodium salt) (Cay-10008318) is a potent and selective cysteinyl leukotriene 1 (CysLT1) receptor antagonist. Formulations containing montelukast are used for the treatment of asthma as well as for the symptoms associated with allergic rhinitis.Formal Name: 1-[[[(1R)-1-[3-[2-(7-chloro-2-quinolinyl)ethyl]phenyl]-3-[2-(1-hydroxy-1-methylethyl)phenyl]propyl]thio]methyl]-cyclopropaneacetic acid.
