Chemical Structure

Levocetirizine Dihydrochloride CAS 130018-87-0 chemical structure

Description

The molecular framework of Levocetirizine Dihydrochloride (C21H25ClN2O3HCl) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Levocetirizine Dihydrochloride (CAS 130018-87-0) is a high-purity analytical reference standard with the molecular formula C21H25ClN2O3HCl and a molecular weight of 425.35 g/mol.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures Levocetirizine Dihydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
