Chemical Structure

Sodium 2,4-pentanedionate hydrate CAS 86891-03-4 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.

CATO supplies Sodium 2,4-pentanedionate hydrate (CAS 86891-03-4), a certified reference material (molecular formula C5H7O2NaH2O, MW 140.11 g/mol) for analytical method development and quality control.

Based on its molecular formula C5H7O2NaH2O, Sodium 2,4-pentanedionate hydrate contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 140.11 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
