Chemical Structure
Description
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.
CATO supplies 2,2,10-Trimethyl-3,4-dihydro-2H-pyrano[2,3-b]quinolin-5(10H)-one (CAS 6391-67-9), a certified reference material (molecular formula C15H17NO2, MW 243.30 g/mol) for analytical method development and quality control.
The molecular framework of 2,2,10-Trimethyl-3,4-dihydro-2H-pyrano[2,3-b]quinolin-5(10H)-one (C15H17NO2) is characterized by a nitrogen-containing heterocyclic scaffold, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
