4-Acetyl-3-methyl-1H-pyrrole-2-carbaldehyde CAS 56015-72-6 chemical structure

Description

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

4-Acetyl-3-methyl-1H-pyrrole-2-carbaldehyde (CAS 56015-72-6), molecular formula C8H9NO2 and molecular weight 151.16 g/mol, is a CATO reference standard with documented purity and traceability.

4-Acetyl-3-methyl-1H-pyrrole-2-carbaldehyde (C8H9NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

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.
