Description
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.
2-((1-(Furan-2-ylmethyl)-5-(p-tolyl)-1H-imidazol-2-yl)thio)-N-methylacetamide (CAS 1206989-23-2), molecular formula C18H19N3O2S and molecular weight 341.43 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-((1-(Furan-2-ylmethyl)-5-(p-tolyl)-1H-imidazol-2-yl)thio)-N-methylacetamide (C18H19N3O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 341.43 g/mol, it falls into the moderately-high-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.
