6-Hydroxy-2-[(5-methoxy-1-methyl-1H-indol-3-yl)methylidene]-7-methyl-2,3-dihydro-1-benzofuran-3-one CAS 929339-33-3

Description

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.

6-Hydroxy-2-[(5-methoxy-1-methyl-1H-indol-3-yl)methylidene]-7-methyl-2,3-dihydro-1-benzofuran-3-one (CAS 929339-33-3), molecular formula C20H17NO4 and molecular weight 335.35 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 6-Hydroxy-2-[(5-methoxy-1-methyl-1H-indol-3-yl)methylidene]-7-methyl-2,3-dihydro-1-benzofuran-3-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 335.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), 6-Hydroxy-2-[(5-methoxy-1-methyl-1H-indol-3-yl)methylidene]-7-methyl-2,3-dihydro-1-benzofuran-3-one 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.
