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.
CATO supplies 1-(2-Chlorophenoxy)-3-((2-methoxyphenyl)sulfonyl)propan-2-ol (CAS 478079-90-2), a certified reference material (molecular formula C16H17ClO5S, MW 356.82 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 1-(2-Chlorophenoxy)-3-((2-methoxyphenyl)sulfonyl)propan-2-ol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 356.82 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.
