Compared with other compounds in its class, the molecular weight of 555.55 g/mol gives 1,3,5-Tris(4-(4H-1,2,4-triazol-4-yl)phenoxy)benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,3,5-Tris(4-(4H-1,2,4-triazol-4-yl)phenoxy)benzene (CAS 1680199-77-2), molecular formula C30H21N9O3 and molecular weight 555.55 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 1,3,5-Tris(4-(4H-1,2,4-triazol-4-yl)phenoxy)benzene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 555.55 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
