Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 133.15 g/mol gives 3-Amino-2-hydroxy-3-methylbutanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Amino-2-hydroxy-3-methylbutanoic acid (CAS 62000-66-2), molecular formula C5H11NO3 and molecular weight 133.15 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 3-Amino-2-hydroxy-3-methylbutanoic acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 133.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
