Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(2R,3S)-1-(bis(4-methoxyphenyl)(phenyl)methoxy)pentane-2,3-diol (CAS 95049-01-7), molecular formula C26H30O5 and molecular weight 422.51 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2R,3S)-1-(bis(4-methoxyphenyl)(phenyl)methoxy)pentane-2,3-diol (C26H30O5) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
As a certified reference material (CRM), (2R,3S)-1-(bis(4-methoxyphenyl)(phenyl)methoxy)pentane-2,3-diol 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.
