Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 315.80 g/mol gives Bumetrizole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Bumetrizole (CAS 3896-11-5) is a high-purity analytical reference standard with the molecular formula C17H18ClN3O and a molecular weight of 315.80 g/mol.
Structurally, Bumetrizole (C17H18ClN3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 315.80 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
