Chemical Structure
Description
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.
6,7-Dihydropyrano[3,4-c]pyrrol-4(2H)-one (CAS 83670-76-2) is a high-purity analytical reference standard with the molecular formula C7H7NO2 and a molecular weight of 137.14 g/mol.
The molecular framework of 6,7-Dihydropyrano[3,4-c]pyrrol-4(2H)-one (C7H7NO2) is characterized by an amino-acid-derived structure, an amide 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 6,7-Dihydropyrano[3,4-c]pyrrol-4(2H)-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.
