Description

Compared with other compounds in its class, the molecular weight of 327.34 g/mol gives 4-Bromo-1,1 inverted exclamation marka:3 inverted exclamation marka,1 inverted exclamation marka inverted exclamation marka-terphenyl 4-Bromo-m-terphenyl 54590-37-3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Bromo-1,1 inverted exclamation marka:3 inverted exclamation marka,1 inverted exclamation marka inverted exclamation marka-terphenyl 4-Bromo-m-terphenyl 54590-37-3 (CAS 54590-37-3), molecular formula C18H31Br and molecular weight 327.34 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-Bromo-1,1 inverted exclamation marka:3 inverted exclamation marka,1 inverted exclamation marka inverted exclamation marka-terphenyl 4-Bromo-m-terphenyl 54590-37-3 (C18H31Br) contains bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 327.34 g/mol, it falls into the moderately-high-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.
