Chemical Structure
Description
The occurrence of 5-bromo-2-(ethylsulfanyl)pyridine is closely related to a nitrile group, sulfur-containing functionality, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-bromo-2-(ethylsulfanyl)pyridine (CAS 127800-66-2), molecular formula C7H8BrNS and molecular weight 218.11 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-bromo-2-(ethylsulfanyl)pyridine (C7H8BrNS) is characterized by a nitrile group, sulfur-containing functionality, bromine substitution, an aromatic ring system. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
CATO manufactures 5-bromo-2-(ethylsulfanyl)pyridine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
