Chemical Structure

(Z)-4-Hydroxytamoxifen CAS 68047-06-3 chemical structure

Description

(Z)-4-Hydroxytamoxifen (CAS 68047-06-3) is a high-purity analytical reference standard with the molecular formula C26H29NO2 and a molecular weight of 387.51 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, (Z)-4-Hydroxytamoxifen is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 387.51 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).

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), (Z)-4-Hydroxytamoxifen 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.
