Chemical Structure
Description
The molecular framework of 5-(Prop-1-yn-1-yl)isobenzofuran-1,3-dione (C11H6O3) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
5-(Prop-1-yn-1-yl)isobenzofuran-1,3-dione (CAS 1240685-26-0) is a high-purity analytical reference standard with the molecular formula C11H6O3 and a molecular weight of 186.16 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 5-(Prop-1-yn-1-yl)isobenzofuran-1,3-dione 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.
