Chemical Structure
Description
(2R)-2-[[(1,1-Dimethylethyl)diphenylsilyl]oxy]butanal (CAS 1309610-38-5) is a high-purity analytical reference standard with the molecular formula C20H26O2Si and a molecular weight of 326.50 g/mol.
The molecular framework of (2R)-2-[[(1,1-Dimethylethyl)diphenylsilyl]oxy]butanal (C20H26O2Si) 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), (2R)-2-[[(1,1-Dimethylethyl)diphenylsilyl]oxy]butanal 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.
