Levocetirizine intermediate is a key chiral precursor in the pharmaceutical synthesis of levocetirizine dihydrochloride, an antihistamine. The core process involves asymmetric hydrogenation or resolution of racemic cetirizine derivatives. Key specifications include CAS 201859-46-7 and molecular formula C20H25ClN2O2.
Store in a cool, dry place below 25°C with controlled humidity. Avoid inhalation of dust; wear appropriate PPE including respirators and chemical-resistant gloves during handling to prevent sensitization.
