Chemical Structure
Description
4-[(2,3-Dihydro-1H-inden-5-yl)oxy]butanoic acid (CAS 929341-05-9), molecular formula C13H16O3 and molecular weight 220.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-[(2,3-Dihydro-1H-inden-5-yl)oxy]butanoic acid (C13H16O3) 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 its high hydrophobicity (logP), 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).
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 4-[(2,3-Dihydro-1H-inden-5-yl)oxy]butanoic acid 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.
