Chemical Structure
Description
CATO supplies 4-(3-Chloro-2-methylpropyl)-2-methylthiophene (CAS 1494649-08-9), a certified reference material (molecular formula C9H13ClS, MW 188.72 g/mol) for analytical method development and quality control.
Structurally, 4-(3-Chloro-2-methylpropyl)-2-methylthiophene (C9H13ClS) contains sulfur-containing functionality, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 188.72 g/mol, it falls into the medium-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.
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.
