Chemical Structure

Raloxifene Impurity 3 CAS 84449-65-0 chemical structure

Description

Raloxifene Impurity 3 (C16H14O6S3) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

Raloxifene Impurity 3 (CAS 84449-65-0) is a high-purity analytical reference standard with the molecular formula C16H14O6S3 and a molecular weight of 398.47 g/mol.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Raloxifene Impurity 3 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
