Chemical Structure
Description
The occurrence of 2-Bromo-3-bromomethylthiophene 2-bromo-3-(bromomethyl)thiophene 40032-76-6 A6690 is closely related to sulfur-containing functionality, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Bromo-3-bromomethylthiophene 2-bromo-3-(bromomethyl)thiophene 40032-76-6 A6690 (CAS 40032-76-6), molecular formula C5H8Br2S and molecular weight 259.99 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Bromo-3-bromomethylthiophene 2-bromo-3-(bromomethyl)thiophene 40032-76-6 A6690 (C5H8Br2S) is characterized by sulfur-containing functionality, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
