3,4,8-Trimethyl-7-(2-oxopropoxy)-2H-chromen-2-one CAS 21861-39-2

Description

The occurrence of 3,4,8-Trimethyl-7-(2-oxopropoxy)-2H-chromen-2-one is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3,4,8-Trimethyl-7-(2-oxopropoxy)-2H-chromen-2-one (CAS 21861-39-2), molecular formula C15H16O4 and molecular weight 260.29 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3,4,8-Trimethyl-7-(2-oxopropoxy)-2H-chromen-2-one (C15H16O4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), 3,4,8-Trimethyl-7-(2-oxopropoxy)-2H-chromen-2-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.
