Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Methoxy-4-(3,4,5-trimethoxyphenethyl)phenol (CAS 101508-50-3), molecular formula C18H22O5 and molecular weight 318.36 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Methoxy-4-(3,4,5-trimethoxyphenethyl)phenol (C18H22O5) is characterized by a flavonoid 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), 2-Methoxy-4-(3,4,5-trimethoxyphenethyl)phenol 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.
