Description
As a certified reference material (CRM), 4-(Isopropylthio)-1-phenylbutan-1-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
4-(Isopropylthio)-1-phenylbutan-1-one (CAS 1184120-10-2), molecular formula C13H18OS and molecular weight 222.35 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(Isopropylthio)-1-phenylbutan-1-one (C13H18OS) is characterized by sulfur-containing functionality, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
