2-(2,5-Dimethyl-1H-pyrrol-1-yl)thiophene-3-carbohydrazide CAS 678139-53-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 235.31 g/mol gives 2-(2,5-Dimethyl-1H-pyrrol-1-yl)thiophene-3-carbohydrazide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(2,5-Dimethyl-1H-pyrrol-1-yl)thiophene-3-carbohydrazide (CAS 678139-53-2), molecular formula C11H13N3OS and molecular weight 235.31 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 2-(2,5-Dimethyl-1H-pyrrol-1-yl)thiophene-3-carbohydrazide is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 235.31 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.
