Chemical Structure
Description
The occurrence of 2-(2,5-Dimethyl-1-(thiazol-2-yl)-1H-pyrrol-3-yl)-N-methyl-2-oxoacetamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(2,5-Dimethyl-1-(thiazol-2-yl)-1H-pyrrol-3-yl)-N-methyl-2-oxoacetamide (CAS 866156-71-0), molecular formula C12H13N3O2S and molecular weight 263.32 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-(2,5-Dimethyl-1-(thiazol-2-yl)-1H-pyrrol-3-yl)-N-methyl-2-oxoacetamide (C12H13N3O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 263.32 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
