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-chloro-4H,5H,6H,7H-thieno[3,2-c]pyridine hydrochloride.
2-chloro-4H,5H,6H,7H-thieno[3,2-c]pyridine hydrochloride (CAS 1909305-72-1), molecular formula C7H8ClNSHCl and molecular weight 210.12 g/mol, is a CATO reference standard with documented purity and traceability.
2-chloro-4H,5H,6H,7H-thieno[3,2-c]pyridine hydrochloride (C7H8ClNSHCl) contains a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
As a certified reference material (CRM), 2-chloro-4H,5H,6H,7H-thieno[3,2-c]pyridine hydrochloride 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.
