Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 172.68 g/mol gives 3-(5-Chloro-2-thienyl)-2-methyl-1-propene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(5-Chloro-2-thienyl)-2-methyl-1-propene (CAS 951885-90-8) is a high-purity analytical reference standard with the molecular formula C8H9ClS and a molecular weight of 172.68 g/mol.
The molecular framework of 3-(5-Chloro-2-thienyl)-2-methyl-1-propene (C8H9ClS) is characterized by sulfur-containing functionality, chlorine substitution, an aromatic ring system. 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. 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.
