Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(2-(1H-indol-3-yl)ethyl)-3-phenylthiourea.
1-(2-(1H-indol-3-yl)ethyl)-3-phenylthiourea (CAS 331631-15-3), molecular formula C17H17N3S and molecular weight 295.40 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 1-(2-(1H-indol-3-yl)ethyl)-3-phenylthiourea is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 295.40 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).
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.
