Chemical Structure
Description
(2-((4-(tert-Butyl)phenyl)diMethylsilyl)phenyl)Methanol (CAS 1398044-30-8), molecular formula C19H26OSi and molecular weight 298.49 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2-((4-(tert-Butyl)phenyl)diMethylsilyl)phenyl)Methanol (C19H26OSi) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
CATO manufactures (2-((4-(tert-Butyl)phenyl)diMethylsilyl)phenyl)Methanol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
