Chemical Structure

2-Hydroxy-2-methylbutane-1,4-dioic acid CAS 597-44-4 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

2-Hydroxy-2-methylbutane-1,4-dioic acid (CAS 597-44-4) is a high-purity analytical reference standard with the molecular formula C5H8O5 and a molecular weight of 148.11 g/mol.

The molecular framework of 2-Hydroxy-2-methylbutane-1,4-dioic acid (C5H8O5) is characterized by a carbohydrate-derived structure. 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 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.
