Chemical Structure
Description
The occurrence of 4-Chloro-2-vinylthiophene is closely related to sulfur-containing functionality, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Chloro-2-vinylthiophene (CAS 1507202-31-4), molecular formula C6H5ClS and molecular weight 144.62 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-Chloro-2-vinylthiophene (C6H5ClS) contains sulfur-containing functionality, chlorine 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 144.62 g/mol, it falls into the low-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.
