Chemical Structure

2-(5-(Furan-2-yl)-1,10b-dihydro-5H-benzo[e]pyrazolo[1,5-c][1,3]oxazin-2-yl)phenol CAS 899973-36-5 chemical structure

Description

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 2-(5-(Furan-2-yl)-1,10b-dihydro-5H-benzo[e]pyrazolo[1,5-c][1,3]oxazin-2-yl)phenol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 332.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO supplies 2-(5-(Furan-2-yl)-1,10b-dihydro-5H-benzo[e]pyrazolo[1,5-c][1,3]oxazin-2-yl)phenol (CAS 899973-36-5), a certified reference material (molecular formula C20H16N2O3, MW 332.35 g/mol) for analytical method development and quality control.

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.
