2-(5-But-3-Yn-2-Yloxy-4-Chloro-2-Fluoro-Phenyl)-4,5,6,7-Tetrahydroisoindole-1,3-Dione CAS 84478-52-4 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 2-(5-But-3-Yn-2-Yloxy-4-Chloro-2-Fluoro-Phenyl)-4,5,6,7-Tetrahydroisoindole-1,3-Dione.

CATO supplies 2-(5-But-3-Yn-2-Yloxy-4-Chloro-2-Fluoro-Phenyl)-4,5,6,7-Tetrahydroisoindole-1,3-Dione (CAS 84478-52-4), a certified reference material (molecular formula C18H15ClFNO3, MW 347.77 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 2-(5-But-3-Yn-2-Yloxy-4-Chloro-2-Fluoro-Phenyl)-4,5,6,7-Tetrahydroisoindole-1,3-Dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 347.77 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-(5-But-3-Yn-2-Yloxy-4-Chloro-2-Fluoro-Phenyl)-4,5,6,7-Tetrahydroisoindole-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.
