(r)-5-(Diethylamino)-2-(1-hydroxyethyl)phenol CAS 1821840-53-2

Description

Compared with other compounds in its class, the molecular weight of 209.28 g/mol gives (r)-5-(Diethylamino)-2-(1-hydroxyethyl)phenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(r)-5-(Diethylamino)-2-(1-hydroxyethyl)phenol (CAS 1821840-53-2), molecular formula C12H19NO2 and molecular weight 209.28 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (r)-5-(Diethylamino)-2-(1-hydroxyethyl)phenol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 209.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
