4-Cyano-3-pentyloxybenzenesulfonyl chloride CAS 942199-55-5

Description

The occurrence of 4-Cyano-3-pentyloxybenzenesulfonyl chloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Cyano-3-pentyloxybenzenesulfonyl chloride (CAS 942199-55-5), molecular formula C12H14ClNO3S and molecular weight 287.76 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C12H14ClNO3S, 4-Cyano-3-pentyloxybenzenesulfonyl chloride contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 287.76 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
