3-((2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)amino)-1-(naphthalen-2-yl)propan-1-one CAS 477334-35-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-((2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)amino)-1-(naphthalen-2-yl)propan-1-one.

3-((2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)amino)-1-(naphthalen-2-yl)propan-1-one (CAS 477334-35-3), molecular formula C21H19NO3 and molecular weight 333.38 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C21H19NO3, 3-((2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)amino)-1-(naphthalen-2-yl)propan-1-one contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 333.38 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

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.
