Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,2'-(Thiophene-2,5-diyl)diacetonitrile.
2,2'-(Thiophene-2,5-diyl)diacetonitrile (CAS 702-22-7), molecular formula C8H6N2S and molecular weight 162.21 g/mol, is a CATO reference standard with documented purity and traceability.
2,2'-(Thiophene-2,5-diyl)diacetonitrile (C8H6N2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its physicochemical properties are representative of its class; 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).
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.
