1,3-Dibromo-5-(dibromomethyl)benzene CAS 256386-08-0

Description

The occurrence of 1,3-Dibromo-5-(dibromomethyl)benzene is closely related to bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,3-Dibromo-5-(dibromomethyl)benzene (CAS 256386-08-0), molecular formula C7H4Br4 and molecular weight 407.72 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7H4Br4, 1,3-Dibromo-5-(dibromomethyl)benzene contains bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 407.72 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
