Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
2-Iodothieno[3,2-c]pyridine (CAS 94226-17-2) is a high-purity analytical reference standard with the molecular formula C7H4INS and a molecular weight of 261.08 g/mol.
2-Iodothieno[3,2-c]pyridine (C7H4INS) contains a nitrile group, sulfur-containing functionality, iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), 2-Iodothieno[3,2-c]pyridine 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.
