5-(1-(4-Chlorophenoxy)ethyl)-1-((4-chlorophenyl)sulfonyl)-1H-pyrazole CAS 321574-13-4

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.

5-(1-(4-Chlorophenoxy)ethyl)-1-((4-chlorophenyl)sulfonyl)-1H-pyrazole (CAS 321574-13-4), molecular formula C17H14Cl2N2O3S and molecular weight 397.28 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 5-(1-(4-Chlorophenoxy)ethyl)-1-((4-chlorophenyl)sulfonyl)-1H-pyrazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 397.28 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
