Chemical Structure
Description
The occurrence of 1-(2,5-Dibromophenyl)thiourea is closely related to a nitrile group, sulfur-containing functionality, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(2,5-Dibromophenyl)thiourea (CAS 854890-84-9) is a high-purity analytical reference standard with the molecular formula C7H6Br2N2S and a molecular weight of 310.01 g/mol.
Structurally, 1-(2,5-Dibromophenyl)thiourea (C7H6Br2N2S) contains a nitrile group, sulfur-containing functionality, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 310.01 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.
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.
