Description
CATO manufactures (R)-2-Amino-1,1,2-triphenylethanol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
(R)-2-Amino-1,1,2-triphenylethanol (CAS 79868-79-4) is a high-purity analytical reference standard with the molecular formula C20H19NO and a molecular weight of 289.37 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, (R)-2-Amino-1,1,2-triphenylethanol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 289.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
