Chemical Structure
Description
Structurally, 1-Bromo-4-butylthiobenzene (C10H13BrS) contains sulfur-containing functionality, 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 245.18 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
1-Bromo-4-butylthiobenzene (CAS 121392-35-6) is a high-purity analytical reference standard with the molecular formula C10H13BrS and a molecular weight of 245.18 g/mol.
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.
