Description

Compared with other compounds in its class, the molecular weight of 271.29 g/mol gives 5-(p-Tolyl)-1H-imidazol-2-amine hemisulfate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-(p-Tolyl)-1H-imidazol-2-amine hemisulfate (CAS 1177340-62-3), molecular formula C10H11N3H2O4S and molecular weight 271.29 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 5-(p-Tolyl)-1H-imidazol-2-amine hemisulfate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 271.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
