(E)-4’’-Hydroxy Tamoxifen CAS 82413-21-6

Description

Compared with other compounds in its class, the molecular weight of 387.51 g/mol gives (E)-4’’-Hydroxy Tamoxifen distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(E)-4’’-Hydroxy Tamoxifen (CAS 82413-21-6), molecular formula C26H29NO2 and molecular weight 387.51 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, (E)-4’’-Hydroxy Tamoxifen 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
