Chemical Structure
Description
5-(1,3-Dioxolan-2-yl)-2-thienyl undecyl ketone (CAS 898772-00-4), molecular formula C19H30O3S and molecular weight 338.50 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(1,3-Dioxolan-2-yl)-2-thienyl undecyl ketone (C19H30O3S) is characterized by a steroid core, a sulfone group, 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.
CATO manufactures 5-(1,3-Dioxolan-2-yl)-2-thienyl undecyl ketone 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.
