Chemical Structure
Description
The occurrence of 1,3-Dimethyl-5-nitrobenzimidazol-2(3H)-one is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,3-Dimethyl-5-nitrobenzimidazol-2(3H)-one (CAS 43027-50-5) is a high-purity analytical reference standard with the molecular formula C9H9N3O3 and a molecular weight of 207.19 g/mol.
1,3-Dimethyl-5-nitrobenzimidazol-2(3H)-one (C9H9N3O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 1,3-Dimethyl-5-nitrobenzimidazol-2(3H)-one 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.
