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.
2-Methyl-6,7-dihydro-1-benzofuran-4(5H)-one dihydrate (CAS 1390654-40-6), molecular formula C9H10O2H2O and molecular weight 168.19 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Methyl-6,7-dihydro-1-benzofuran-4(5H)-one dihydrate (C9H10O2H2O) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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 2-Methyl-6,7-dihydro-1-benzofuran-4(5H)-one dihydrate 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.
