Chemical Structure
Description
The occurrence of 8-Chloro-1,2,3,4-tetrahydropyrido[3,4-b]pyrazine is closely related to a nitrile group, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 8-Chloro-1,2,3,4-tetrahydropyrido[3,4-b]pyrazine (CAS 1849346-01-5), a certified reference material (molecular formula C7H8ClN3, MW 169.61 g/mol) for analytical method development and quality control.
8-Chloro-1,2,3,4-tetrahydropyrido[3,4-b]pyrazine (C7H8ClN3) contains a nitrile group, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
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.
