6-Methyl-8-nitro-4-oxo-4H-chromene-3-carbaldehyde CAS 879559-54-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Methyl-8-nitro-4-oxo-4H-chromene-3-carbaldehyde.

6-Methyl-8-nitro-4-oxo-4H-chromene-3-carbaldehyde (CAS 879559-54-3) is a high-purity analytical reference standard with the molecular formula C11H7NO5 and a molecular weight of 233.18 g/mol.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 6-Methyl-8-nitro-4-oxo-4H-chromene-3-carbaldehyde is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 233.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
