Chemical Structure
Description
(3R,4S)-1,2,3,4-Tetrahydro-4-(3-isopropoxyphenyl)-1,3,4-trimethylpyridine (CAS 143919-33-9), molecular formula C17H25NO and molecular weight 259.39 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (3R,4S)-1,2,3,4-Tetrahydro-4-(3-isopropoxyphenyl)-1,3,4-trimethylpyridine (C17H25NO) is characterized by a steroid core, an amide 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures (3R,4S)-1,2,3,4-Tetrahydro-4-(3-isopropoxyphenyl)-1,3,4-trimethylpyridine 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.
