Chemical Structure
Description
Cetirizine Lactose Ester Hydrochloride Salt (a/b-mixture, mixture of diastereomers) (CAS CATO-C4X-158214), molecular formula C33H45ClN2O13HCl and molecular weight 749.63 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Cetirizine Lactose Ester Hydrochloride Salt (a/b-mixture, mixture of diastereomers) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 749.63 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 Cetirizine Lactose Ester Hydrochloride Salt (a/b-mixture, mixture of diastereomers) 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.
