Chemical Structure

Acetoacetic acid CAS 541-50-4 chemical structure

Description

CATO supplies Acetoacetic acid (CAS 541-50-4), a certified reference material (molecular formula C4H6O3, MW 102.09 g/mol) for analytical method development and quality control.

The molecular framework of Acetoacetic acid (C4H6O3) is characterized by a carboxylic acid group, 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.

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), Acetoacetic acid 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.
