Chemical Structure

3-(5-methylfuran-2-yl)butanal CAS 31704-80-0 chemical structure

Description

3-(5-methylfuran-2-yl)butanal (CAS 31704-80-0) is a high-purity analytical reference standard with the molecular formula C9H16O2 and a molecular weight of 156.22 g/mol.

Structurally, 3-(5-methylfuran-2-yl)butanal (C9H16O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 156.22 g/mol, it falls into the medium-molecular-weight range.

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.
