Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Hydroxyvaleric Acid Sodium Salt.
4-Hydroxyvaleric Acid Sodium Salt (CAS 56279-37-9) is a high-purity analytical reference standard with the molecular formula C5H9O3Na and a molecular weight of 140.11 g/mol.
Based on its molecular formula C5H9O3Na, 4-Hydroxyvaleric Acid Sodium Salt 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
