Chemical Structure

Ostreasterol CAS 474-63-5 chemical structure

Description

As a certified reference material (CRM), Ostreasterol 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.

CATO supplies Ostreasterol (CAS 474-63-5), a certified reference material (molecular formula C28H46O, MW 398.66 g/mol) for analytical method development and quality control.

Based on its molecular formula C28H46O, Ostreasterol contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 398.66 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

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.
