Chemical Structure
Description
5-Chloro-2-(4-methylphenoxy)aniline hydrochloride (CAS 1173051-49-4), molecular formula C13H12ClNOHCl and molecular weight 270.15 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 5-Chloro-2-(4-methylphenoxy)aniline hydrochloride is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 270.15 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.
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.
