Cyclo(L-Pro-L-Trp-) CAS 38136-70-8

Description

Cyclo(L-Pro-L-Trp-) (CAS 38136-70-8), molecular formula C16H17N3O2 and molecular weight 283.33 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, Cyclo(L-Pro-L-Trp-) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 283.33 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.

CATO manufactures Cyclo(L-Pro-L-Trp-) 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.
