Chemical Structure
Description
The molecular framework of 4-(2-Thiophen-2-yl-benzyl)-tetrahydro-pyran-4-carboxylic acid (C17H18O3S) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
4-(2-Thiophen-2-yl-benzyl)-tetrahydro-pyran-4-carboxylic acid (CAS 1316221-73-4), molecular formula C17H18O3S and molecular weight 302.39 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-(2-Thiophen-2-yl-benzyl)-tetrahydro-pyran-4-carboxylic acid 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.
