Chemical Structure

2-Methyl-5-nitrofuran CAS 823-74-5 chemical structure

Description

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 2-Methyl-5-nitrofuran is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 127.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

2-Methyl-5-nitrofuran (CAS 823-74-5) is a high-purity analytical reference standard with the molecular formula C5H5NO3 and a molecular weight of 127.10 g/mol.

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.
