Chemical Structure
Description
CATO supplies 2,3,4,9-Tetrahydro-3,9,9-trimethyl-6-pentyl-1H-xanthen-8-ol (CAS 18110-59-3), a certified reference material (molecular formula C21H30O2, MW 314.46 g/mol) for analytical method development and quality control.
The molecular framework of 2,3,4,9-Tetrahydro-3,9,9-trimethyl-6-pentyl-1H-xanthen-8-ol (C21H30O2) is characterized by a steroid core, 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 2,3,4,9-Tetrahydro-3,9,9-trimethyl-6-pentyl-1H-xanthen-8-ol 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.
