Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(Methylthio)-4,5-dihydro-1H-imidazole Hydroiodide.
2-(Methylthio)-4,5-dihydro-1H-imidazole Hydroiodide (CAS 5464-11-9) is a high-purity analytical reference standard with the molecular formula HIC4H8N2S and a molecular weight of 244.09 g/mol.
Based on its molecular formula HIC4H8N2S, 2-(Methylthio)-4,5-dihydro-1H-imidazole Hydroiodide contains sulfur-containing functionality, iodine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 244.09 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
