2-amino-2-(1H-1,2,3,4-tetrazol-5-yl)acetic acid CAS 138199-51-6

Description

2-amino-2-(1H-1,2,3,4-tetrazol-5-yl)acetic acid (CAS 138199-51-6) is a high-purity analytical reference standard with the molecular formula C3H9N5O2 and a molecular weight of 147.14 g/mol.

Based on its molecular formula C3H9N5O2, 2-amino-2-(1H-1,2,3,4-tetrazol-5-yl)acetic acid contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 147.14 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.
