Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,5-Dibromo-3-decylthiophene.
2,5-Dibromo-3-decylthiophene (CAS 158956-23-1) is a high-purity analytical reference standard with the molecular formula C14H22Br2S and a molecular weight of 382.20 g/mol.
Owing to sulfur-containing functionality, bromine substitution, 2,5-Dibromo-3-decylthiophene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 382.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
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.
