1H-Imidazole, 2-ethenyl-4,5-dihydro-, homopolymer, sulfate CAS 30394-74-2

Description

1H-Imidazole, 2-ethenyl-4,5-dihydro-, homopolymer, sulfate (CAS 30394-74-2) is a high-purity analytical reference standard with the molecular formula H2O4SC5H8N2 and a molecular weight of 194.20 g/mol.

Based on its molecular formula H2O4SC5H8N2, 1H-Imidazole, 2-ethenyl-4,5-dihydro-, homopolymer, sulfate contains a carbohydrate-derived structure, an amide group, a sulfone group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 194.20 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.
