Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 209.15 g/mol gives Ammonium 3,4-dicarboxy-3-hydroxybutanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Ammonium 3,4-dicarboxy-3-hydroxybutanoate (CAS 4450-94-6), a certified reference material (molecular formula C6H7O7H4N, MW 209.15 g/mol) for analytical method development and quality control.
Structurally, Ammonium 3,4-dicarboxy-3-hydroxybutanoate (C6H7O7H4N) contains a carbohydrate-derived structure, an amide group. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 209.15 g/mol, it falls into the medium-molecular-weight range. 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.
