Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-[5-(Thiophene-2-carbonyl)thiophen-2-yl]acetonitrile.
2-[5-(Thiophene-2-carbonyl)thiophen-2-yl]acetonitrile (CAS 339098-98-5), molecular formula C11H7NOS2 and molecular weight 233.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-[5-(Thiophene-2-carbonyl)thiophen-2-yl]acetonitrile (C11H7NOS2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
