Chemical Structure
Description
The occurrence of 2-Chloro-6-methyl-1,4-diazine 2-chloro-6-methyl-pyrazine 2-chloro-6-methylpyrazine 38557-71-0 is closely related to chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-Chloro-6-methyl-1,4-diazine 2-chloro-6-methyl-pyrazine 2-chloro-6-methylpyrazine 38557-71-0 (CAS 38557-71-0), a certified reference material (molecular formula C5H11ClN2, MW 134.61 g/mol) for analytical method development and quality control.
2-Chloro-6-methyl-1,4-diazine 2-chloro-6-methyl-pyrazine 2-chloro-6-methylpyrazine 38557-71-0 (C5H11ClN2) contains chlorine substitution. 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.
