Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 196.11 g/mol gives 3-Bromo-6-mercaptopyridine 5-Bromopyridine-2-thiol 56673-34-8 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Bromo-6-mercaptopyridine 5-Bromopyridine-2-thiol 56673-34-8 (CAS 56673-34-8), a certified reference material (molecular formula C5H10BrNS, MW 196.11 g/mol) for analytical method development and quality control.
The molecular framework of 3-Bromo-6-mercaptopyridine 5-Bromopyridine-2-thiol 56673-34-8 (C5H10BrNS) is characterized by sulfur-containing functionality, 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.
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), 3-Bromo-6-mercaptopyridine 5-Bromopyridine-2-thiol 56673-34-8 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.
