Description
As a certified reference material (CRM), 2-Chloro-6-(4-(methylsulfonyl)phenoxy)pyrazine 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.
2-Chloro-6-(4-(methylsulfonyl)phenoxy)pyrazine (CAS 1178612-96-8) is a high-purity analytical reference standard with the molecular formula C11H9ClN2O3S and a molecular weight of 284.72 g/mol.
2-Chloro-6-(4-(methylsulfonyl)phenoxy)pyrazine (C11H9ClN2O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
