4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]methyl}phenyl 2-chlorobenzene-1-sulfonate CAS 338416-34-5

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.

4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]methyl}phenyl 2-chlorobenzene-1-sulfonate (CAS 338416-34-5) is a high-purity analytical reference standard with the molecular formula C19H12Cl2F3NO3S and a molecular weight of 462.27 g/mol.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]methyl}phenyl 2-chlorobenzene-1-sulfonate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 462.27 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.
