Chemical Structure
Description
2-Oxo-3-(2-oxopropyl)-2,3-dihydrobenzo[d]oxazole-5-sulfonamide (CAS 54080-57-8) is a high-purity analytical reference standard with the molecular formula C10H10N2O5S and a molecular weight of 270.26 g/mol.
The molecular framework of 2-Oxo-3-(2-oxopropyl)-2,3-dihydrobenzo[d]oxazole-5-sulfonamide (C10H10N2O5S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2-Oxo-3-(2-oxopropyl)-2,3-dihydrobenzo[d]oxazole-5-sulfonamide 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.
