Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Bromo-3,5-difluoro-4-(methylsulfanyl)benzene.
1-Bromo-3,5-difluoro-4-(methylsulfanyl)benzene (CAS 648905-87-7) is a high-purity analytical reference standard with the molecular formula C7H5BrF2S and a molecular weight of 239.08 g/mol.
Structurally, 1-Bromo-3,5-difluoro-4-(methylsulfanyl)benzene (C7H5BrF2S) contains sulfur-containing functionality, fluorine/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 239.08 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
