Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,2-dibromo-3-isothiocyanatopropane 2,3-Dibromopropyl isothiocyanate 51784-10-2 (CAS 51784-10-2) is a high-purity analytical reference standard with the molecular formula C4H5Br2NS and a molecular weight of 258.96 g/mol.
Structurally, 1,2-dibromo-3-isothiocyanatopropane 2,3-Dibromopropyl isothiocyanate 51784-10-2 (C4H5Br2NS) contains a nitrile group, sulfur-containing functionality, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 258.96 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
