Chemical Structure

Sodium 4-hydroxy-4-methylpentanoate CAS 581099-89-0 chemical structure

Description

Sodium 4-hydroxy-4-methylpentanoate (CAS 581099-89-0), molecular formula C6H11NaO3 and molecular weight 154.14 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C6H11NaO3, Sodium 4-hydroxy-4-methylpentanoate 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 154.14 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
