Chemical Structure

(2S)-3-tert-Butyldiphenylsilyloxy-2-methyl-1-propanol CAS 120346-83-0 chemical structure

Description

The occurrence of (2S)-3-tert-Butyldiphenylsilyloxy-2-methyl-1-propanol is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(2S)-3-tert-Butyldiphenylsilyloxy-2-methyl-1-propanol (CAS 120346-83-0), molecular formula C20H28O2Si and molecular weight 328.52 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (2S)-3-tert-Butyldiphenylsilyloxy-2-methyl-1-propanol (C20H28O2Si) 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), (2S)-3-tert-Butyldiphenylsilyloxy-2-methyl-1-propanol 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.
