Chemical Structure

(But-3-yn-2-yloxy)(tert-butyl)dimethylsilane CAS 125494-93-1 chemical structure

Description

(But-3-yn-2-yloxy)(tert-butyl)dimethylsilane (CAS 125494-93-1) is a high-purity analytical reference standard with the molecular formula C10H20OSi and a molecular weight of 184.35 g/mol.

The molecular framework of (But-3-yn-2-yloxy)(tert-butyl)dimethylsilane (C10H20OSi) is characterized by 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 (But-3-yn-2-yloxy)(tert-butyl)dimethylsilane 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.
