Chemical Structure
Description
CATO supplies 5-Hydroxy-4-oxo-4H-chromene-3-carbaldehyde (CAS 153474-15-8), a certified reference material (molecular formula C10H6O4, MW 190.15 g/mol) for analytical method development and quality control.
Structurally, 5-Hydroxy-4-oxo-4H-chromene-3-carbaldehyde (C10H6O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 190.15 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
