5-Methoxy-4-oxo-4H-pyran-2-carbaldehyde CAS 35438-43-8

Description

The occurrence of 5-Methoxy-4-oxo-4H-pyran-2-carbaldehyde is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5-Methoxy-4-oxo-4H-pyran-2-carbaldehyde (CAS 35438-43-8), a certified reference material (molecular formula C7H6O4, MW 154.12 g/mol) for analytical method development and quality control.

Based on its molecular formula C7H6O4, 5-Methoxy-4-oxo-4H-pyran-2-carbaldehyde contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 154.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
