Tolterodine Impurity 18 CAS 124935-89-3

Description

The occurrence of Tolterodine Impurity 18 is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Tolterodine Impurity 18 (CAS 124935-89-3) is a certified pharmaceutical impurity reference standard with the molecular formula C23H33NOC4H4O4 and a molecular weight of 455.59 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Tolterodine Impurity 18 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 455.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

CATO manufactures Tolterodine Impurity 18 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.
