Chemical Structure
Description
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.
7-Chloro-4-iodothieno[2,3-c]pyridine (CAS 1360892-46-1), molecular formula C7H3ClINS and molecular weight 295.53 g/mol, is a CATO reference standard with documented purity and traceability.
7-Chloro-4-iodothieno[2,3-c]pyridine (C7H3ClINS) contains a nitrile group, sulfur-containing functionality, chlorine/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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
