Chemical Structure

Lesinurad Impurity 13 CAS CATO-C4X-147813 chemical structure

Description

The occurrence of Lesinurad Impurity 13 is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Lesinurad Impurity 13 (CAS CATO-C4X-147813) is a certified pharmaceutical impurity reference standard with the molecular formula C17H14BrN3O2S and a molecular weight of 404.28 g/mol.

Structurally, Lesinurad Impurity 13 (C17H14BrN3O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 404.28 g/mol, it falls into the moderately-high-molecular-weight range. 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.

CATO manufactures Lesinurad Impurity 13 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.
