Poly(oxy-1,2-ethanediyl), .alpha.-[2,4,6-tris(2-methylpropyl)phenyl]-.omega.-hydroxy- (CAS 72987-43-0) is a high-purity analytical reference standard with the molecular formula C20H34O2 and a molecular weight of 306.48 g/mol.
The molecular framework of Poly(oxy-1,2-ethanediyl), .alpha.-[2,4,6-tris(2-methylpropyl)phenyl]-.omega.-hydroxy- (C20H34O2) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Poly(oxy-1,2-ethanediyl), .alpha.-[2,4,6-tris(2-methylpropyl)phenyl]-.omega.-hydroxy- 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.
