Chemical Structure

4-bromo-7-chlorothieno[2,3-c]pyridine CAS 1803571-85-8 chemical structure

Description

The occurrence of 4-bromo-7-chlorothieno[2,3-c]pyridine is closely related to a nitrile group, sulfur-containing functionality, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-bromo-7-chlorothieno[2,3-c]pyridine (CAS 1803571-85-8), a certified reference material (molecular formula C7H11BrClNS, MW 256.59 g/mol) for analytical method development and quality control.

The molecular framework of 4-bromo-7-chlorothieno[2,3-c]pyridine (C7H11BrClNS) is characterized by a nitrile group, sulfur-containing functionality, chlorine/bromine 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. 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), 4-bromo-7-chlorothieno[2,3-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.
