Ebastine Impurity N2 CAS 43076-61-5 chemical structure

Description

CATO manufactures Ebastine Impurity N2 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.

Ebastine Impurity N2 (CAS 43076-61-5) is a certified pharmaceutical impurity reference standard with the molecular formula C14H19ClO and a molecular weight of 238.76 g/mol.

Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, Ebastine Impurity N2 is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 238.76 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
