Chemical Structure

3-Bromo-6-chloro-2-methylquinoxaline CAS 1504582-47-1 chemical structure

Description

3-Bromo-6-chloro-2-methylquinoxaline (CAS 1504582-47-1), molecular formula C9H6BrClN2 and molecular weight 257.51 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-Bromo-6-chloro-2-methylquinoxaline (C9H6BrClN2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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-chloro-2-methylquinoxaline 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.
