Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(3-Cyano-4,5,6,7-tetrahydrobenzo[b]thiophen-2-yl)-1H-pyrrole-2-carbonitrile.
1-(3-Cyano-4,5,6,7-tetrahydrobenzo[b]thiophen-2-yl)-1H-pyrrole-2-carbonitrile (CAS 331760-60-2), molecular formula C14H11N3S and molecular weight 253.32 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 1-(3-Cyano-4,5,6,7-tetrahydrobenzo[b]thiophen-2-yl)-1H-pyrrole-2-carbonitrile is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 253.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
