Chemical Structure

2,4-Dimethylfuran-3-carbaldehyde CAS 75002-34-5 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.

2,4-Dimethylfuran-3-carbaldehyde (CAS 75002-34-5) is a high-purity analytical reference standard with the molecular formula C7H8O2 and a molecular weight of 124.14 g/mol.

Structurally, 2,4-Dimethylfuran-3-carbaldehyde (C7H8O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 124.14 g/mol, it falls into the low-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
