Ammonium 3-carboxypropanoate CAS 38457-08-8

Description

Compared with other compounds in its class, the molecular weight of 135.12 g/mol gives Ammonium 3-carboxypropanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ammonium 3-carboxypropanoate (CAS 38457-08-8), molecular formula C4H5O4H4N and molecular weight 135.12 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C4H5O4H4N, Ammonium 3-carboxypropanoate 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 135.12 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.

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.
