2-Chloro-7-iodo-5-(phenylsulfonyl)-5H-pyrrolo[2,3-b]pyrazine (CAS 1262310-65-5) is a high-purity analytical reference standard with the molecular formula C12H7ClIN3O2S and a molecular weight of 419.63 g/mol.
2-Chloro-7-iodo-5-(phenylsulfonyl)-5H-pyrrolo[2,3-b]pyrazine (C12H7ClIN3O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/iodine 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.
