Chemical Structure
Description
5-(5-Formyl-1-methyl-1H-pyrrol-2-yl)nicotinonitrile (CAS 1393709-49-3) is a high-purity analytical reference standard with the molecular formula C12H9N3O and a molecular weight of 211.22 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 5-(5-Formyl-1-methyl-1H-pyrrol-2-yl)nicotinonitrile is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 211.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
