CATO manufactures 2-((6,8-Dichloro-4-oxo-4H-chromen-3-yl)methylene)-1H-indene-1,3(2H)-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.

2-((6,8-Dichloro-4-oxo-4H-chromen-3-yl)methylene)-1H-indene-1,3(2H)-dione (CAS 1024223-96-8) is a high-purity analytical reference standard with the molecular formula C19H8Cl2O4 and a molecular weight of 371.17 g/mol.

Structurally, 2-((6,8-Dichloro-4-oxo-4H-chromen-3-yl)methylene)-1H-indene-1,3(2H)-dione (C19H8Cl2O4) contains a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 371.17 g/mol, it falls into the moderately-high-molecular-weight range. 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.
