Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 314.80 g/mol gives 1,3,5-Tribromobenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,3,5-Tribromobenzene (CAS 626-39-1), molecular formula C6H3Br3 and molecular weight 314.80 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1,3,5-Tribromobenzene (C6H3Br3) contains bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 314.80 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1,3,5-Tribromobenzene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
