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 5-Iodobenzo[b]thiophene-2-carbonitrile.
5-Iodobenzo[b]thiophene-2-carbonitrile (CAS 195607-62-6), molecular formula C9H4INS and molecular weight 285.10 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Iodobenzo[b]thiophene-2-carbonitrile (C9H4INS) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.
As a certified reference material (CRM), 5-Iodobenzo[b]thiophene-2-carbonitrile meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
