Chemical Structure
Description
The molecular framework of 2-((3-Oxo-1,3-dihydroisobenzofuran-1-yl)oxy)acetic acid (C10H8O5) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 2-((3-Oxo-1,3-dihydroisobenzofuran-1-yl)oxy)acetic acid (CAS 61133-41-3), a certified reference material (molecular formula C10H8O5, MW 208.17 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
