Chemical Structure

1,4-Butanedione CAS 4440-92-0 chemical structure

Description

As a certified reference material (CRM), 1,4-Butanedione 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.

1,4-Butanedione (CAS 4440-92-0), molecular formula C22H26O6 and molecular weight 386.44 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,4-Butanedione (C22H26O6) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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.
