Chemical Structure
Description
The occurrence of 3-Isopropoxy-4-(pyrrolidin-1-ylmethyl)-9H-xanthen-9-one is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-Isopropoxy-4-(pyrrolidin-1-ylmethyl)-9H-xanthen-9-one (CAS 58741-68-7), a certified reference material (molecular formula C21H23NO3, MW 337.41 g/mol) for analytical method development and quality control.
The molecular framework of 3-Isopropoxy-4-(pyrrolidin-1-ylmethyl)-9H-xanthen-9-one (C21H23NO3) 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
