Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
CATO supplies 6-Bromo-1,2,3,4-tetrahydropyrido[2,3-b]pyrazine (CAS 1935357-99-5), a certified reference material (molecular formula C7H8BrN3, MW 214.06 g/mol) for analytical method development and quality control.
The molecular framework of 6-Bromo-1,2,3,4-tetrahydropyrido[2,3-b]pyrazine (C7H8BrN3) is characterized by a nitrile group, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
