Chemical Structure
Description
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, Cyclohexylmethyl 5-chlorothiophene-2-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 258.76 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Cyclohexylmethyl 5-chlorothiophene-2-carboxylate (CAS 1448433-72-4), molecular formula C12H15ClO2S and molecular weight 258.76 g/mol, is a CATO reference standard with documented purity and traceability.
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.
