Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 1-(5-Chloro-2-aminophenyl)-1-phenylethanol is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 247.72 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).
1-(5-Chloro-2-aminophenyl)-1-phenylethanol (CAS 3158-98-3), molecular formula C14H14ClNO and molecular weight 247.72 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.
