Chemical Structure

[5-(1-Benzofuran-2-yl)isoxazol-3-yl]acetic acid CAS 1105191-74-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including [5-(1-Benzofuran-2-yl)isoxazol-3-yl]acetic acid.

[5-(1-Benzofuran-2-yl)isoxazol-3-yl]acetic acid (CAS 1105191-74-9) is a high-purity analytical reference standard with the molecular formula C13H9NO4 and a molecular weight of 243.21 g/mol.

The molecular framework of [5-(1-Benzofuran-2-yl)isoxazol-3-yl]acetic acid (C13H9NO4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), [5-(1-Benzofuran-2-yl)isoxazol-3-yl]acetic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
