The occurrence of 2-(4-(4-Chlorophenyl)-2-methyl-3-oxo-1,2,4-oxadiazolidin-5-yl)acetic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(4-(4-Chlorophenyl)-2-methyl-3-oxo-1,2,4-oxadiazolidin-5-yl)acetic acid (CAS 217466-63-2) is a high-purity analytical reference standard with the molecular formula C11H11ClN2O4 and a molecular weight of 270.67 g/mol.
2-(4-(4-Chlorophenyl)-2-methyl-3-oxo-1,2,4-oxadiazolidin-5-yl)acetic acid (C11H11ClN2O4) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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-(4-(4-Chlorophenyl)-2-methyl-3-oxo-1,2,4-oxadiazolidin-5-yl)acetic acid 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.
