Chemical Structure
Description
The occurrence of 3-Bromothioanisole is closely related to sulfur-containing functionality, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Bromothioanisole (CAS 33733-73-2) is a high-purity analytical reference standard with the molecular formula C7H7BrS and a molecular weight of 203.10 g/mol.
Structurally, 3-Bromothioanisole (C7H7BrS) 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 203.10 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 3-Bromothioanisole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
