Chemical Structure
Description
Based on its molecular formula C7H11N3OSHCl, {[(dimethyl-1,2-oxazol-4-yl)methyl]sulfanyl}methanimidamide hydrochloride contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 221.70 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
{[(dimethyl-1,2-oxazol-4-yl)methyl]sulfanyl}methanimidamide hydrochloride (CAS 136389-69-0), molecular formula C7H11N3OSHCl and molecular weight 221.70 g/mol, is a CATO reference standard with documented purity and traceability.
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.
