Chemical Structure
Description
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.
2-[(4-Chlorophenyl)sulfanyl]-2-methylpropanal (CAS 56421-90-0), molecular formula C10H11ClOS and molecular weight 214.71 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2-[(4-Chlorophenyl)sulfanyl]-2-methylpropanal is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 214.71 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.
