128569-20-0 2-[[[(4-chloro-6-methoxy-2-pyrimidinyl)amino]-oxomethyl]sulfamoyl]benzoic acid methyl ester A805842 methyl 2-[(4-chloranyl-6-methoxy-pyrimidin-2-yl)carbamoylsulfamoyl]benzoate (CAS 128569-20-0) is a high-purity analytical reference standard with the molecular formula C14H13ClN4O6S and a molecular weight of 400.79 g/mol.
The molecular framework of 128569-20-0 2-[[[(4-chloro-6-methoxy-2-pyrimidinyl)amino]-oxomethyl]sulfamoyl]benzoic acid methyl ester A805842 methyl 2-[(4-chloranyl-6-methoxy-pyrimidin-2-yl)carbamoylsulfamoyl]benzoate (C14H13ClN4O6S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
As a certified reference material (CRM), 128569-20-0 2-[[[(4-chloro-6-methoxy-2-pyrimidinyl)amino]-oxomethyl]sulfamoyl]benzoic acid methyl ester A805842 methyl 2-[(4-chloranyl-6-methoxy-pyrimidin-2-yl)carbamoylsulfamoyl]benzoate 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.
