Methyl 4-(3,4-dichloro-2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)benzoate CAS 685543-36-6

Description

Compared with other compounds in its class, the molecular weight of 300.09 g/mol gives Methyl 4-(3,4-dichloro-2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)benzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Methyl 4-(3,4-dichloro-2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)benzoate (CAS 685543-36-6), a certified reference material (molecular formula C12H7Cl2NO4, MW 300.09 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Methyl 4-(3,4-dichloro-2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)benzoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 300.09 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).

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

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.
