Chemical Structure
Description
4-((5-(p-Tolyloxy)pentyl)oxy)aniline hydrochloride (CAS 101781-61-7), molecular formula C18H24NO2Cl and molecular weight 321.84 g/mol, is a CATO reference standard with documented purity and traceability.
4-((5-(p-Tolyloxy)pentyl)oxy)aniline hydrochloride (C18H24NO2Cl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-((5-(p-Tolyloxy)pentyl)oxy)aniline hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
