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-(Pyridin-4-yl)-1H-pyrrole-3-carbonitrile (CAS 87388-67-8), molecular formula C10H7N3 and molecular weight 169.18 g/mol, is a CATO reference standard with documented purity and traceability.
4-(Pyridin-4-yl)-1H-pyrrole-3-carbonitrile (C10H7N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
