CATO supplies 1-[(1R,2R)-2-(Hydroxymethyl)-1H,2H,3H-naphtho[2,1-b]pyran-1-yl]-1,3-dimethylthiourea (CAS 321574-21-4), a certified reference material (molecular formula C17H20N2O2S, MW 316.42 g/mol) for analytical method development and quality control.
The molecular framework of 1-[(1R,2R)-2-(Hydroxymethyl)-1H,2H,3H-naphtho[2,1-b]pyran-1-yl]-1,3-dimethylthiourea (C17H20N2O2S) is characterized by a steroid core, an amide group, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
