(4-Methoxymethoxy-phenylethynyl)-trimethylsilane (CAS 162271-44-5) is a high-purity analytical reference standard with the molecular formula C13H18O2Si and a molecular weight of 234.37 g/mol.
The molecular framework of (4-Methoxymethoxy-phenylethynyl)-trimethylsilane (C13H18O2Si) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
CATO manufactures (4-Methoxymethoxy-phenylethynyl)-trimethylsilane 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.
