Chemical Structure
Description
Oxirane, 2-methyl-, polymer with oxirane, mono(4-dodecylphenyl) ether (CAS 63303-00-4), molecular formula C20H32OC3H6O and molecular weight 346.56 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Oxirane, 2-methyl-, polymer with oxirane, mono(4-dodecylphenyl) ether (C20H32OC3H6O) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Oxirane, 2-methyl-, polymer with oxirane, mono(4-dodecylphenyl) ether 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.
