2-Chloro-n-(7-nitro-3-oxo-3,4-dihydro-2h-1,4-benzoxazin-6-yl)acetamide (CAS 1306603-88-2), molecular formula C10H8ClN3O5 and molecular weight 285.64 g/mol, is a CATO reference standard with documented purity and traceability.
2-Chloro-n-(7-nitro-3-oxo-3,4-dihydro-2h-1,4-benzoxazin-6-yl)acetamide (C10H8ClN3O5) contains a nitrogen-containing heterocyclic scaffold, an amide 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 2-Chloro-n-(7-nitro-3-oxo-3,4-dihydro-2h-1,4-benzoxazin-6-yl)acetamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
