Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
468095-88-7 Sulfuric acid--1-ethyl-1H-imidazole (1/1) DTXSID90740286 (CAS 468095-88-7), molecular formula H2O4SC5H8N2 and molecular weight 194.20 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 468095-88-7 Sulfuric acid--1-ethyl-1H-imidazole (1/1) DTXSID90740286 (H2O4SC5H8N2) contains a carbohydrate-derived structure, an amide group, a sulfone group. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 194.20 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
