Chemical Structure
Description
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.
(S)-(3-Amino-4-methoxy-4-oxobutyl)boronic acid (CAS 390402-06-9), molecular formula C5H12BNO4 and molecular weight 160.96 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C5H12BNO4, (S)-(3-Amino-4-methoxy-4-oxobutyl)boronic acid contains a carbohydrate-derived structure, an amide group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 160.96 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
