Chemical Structure

4-Hydroxybut-2-enoic acid CAS 4013-24-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 102.09 g/mol gives 4-Hydroxybut-2-enoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Hydroxybut-2-enoic acid (CAS 4013-24-5), molecular formula C4H6O3 and molecular weight 102.09 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Hydroxybut-2-enoic 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
