2-(1,3-Dioxoisoindolin-2-yl)-3-hydroxybutanoic acid CAS 43018-29-7

Description

2-(1,3-Dioxoisoindolin-2-yl)-3-hydroxybutanoic acid (CAS 43018-29-7), molecular formula C12H11NO5 and molecular weight 249.22 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 2-(1,3-Dioxoisoindolin-2-yl)-3-hydroxybutanoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 249.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 2-(1,3-Dioxoisoindolin-2-yl)-3-hydroxybutanoic 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.
