Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-[5-(4-Tert-butylphenyl)-2-thienyl]ethanone (CAS 893738-24-4) is a high-purity analytical reference standard with the molecular formula C16H18OS and a molecular weight of 258.38 g/mol.
The molecular framework of 1-[5-(4-Tert-butylphenyl)-2-thienyl]ethanone (C16H18OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, a polycyclic aromatic 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).
CATO manufactures 1-[5-(4-Tert-butylphenyl)-2-thienyl]ethanone 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.
