Chemical Structure

2,3-Bis(3,4-Dimethoxybenzyl)butyrolactone CAS 25488-59-9 chemical structure

Description

2,3-Bis(3,4-Dimethoxybenzyl)butyrolactone (CAS 25488-59-9), molecular formula C22H26O6 and molecular weight 386.44 g/mol, is a CATO reference standard with documented purity and traceability.

2,3-Bis(3,4-Dimethoxybenzyl)butyrolactone (C22H26O6) contains a flavonoid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 2,3-Bis(3,4-Dimethoxybenzyl)butyrolactone 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.
