Sodium 4-methyl-2-oxo-2H-chromen-7-olate CAS 5980-33-6

Description

The occurrence of Sodium 4-methyl-2-oxo-2H-chromen-7-olate 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.

Sodium 4-methyl-2-oxo-2H-chromen-7-olate (CAS 5980-33-6), molecular formula C10H7O3Na and molecular weight 198.15 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C10H7O3Na, Sodium 4-methyl-2-oxo-2H-chromen-7-olate 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 198.15 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
