137201-62-8 Spinorphin L-Threonine, N-(N-(1-(N-(N-(N-L-leucyl-L-valyl)-L-valyl)-L-tyrosyl)-L-prolyl)-L-tryptophyl)- Leucyl-valyl-valyl-tyrosyl-prolyl-tryptophyl-threonine Leu-val-val-tyr-pro-trp-thr CAS 137201-62-8

Description

The occurrence of 137201-62-8 Spinorphin L-Threonine, N-(N-(1-(N-(N-(N-L-leucyl-L-valyl)-L-valyl)-L-tyrosyl)-L-prolyl)-L-tryptophyl)- Leucyl-valyl-valyl-tyrosyl-prolyl-tryptophyl-threonine Leu-val-val-tyr-pro-trp-thr is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 137201-62-8 Spinorphin L-Threonine, N-(N-(1-(N-(N-(N-L-leucyl-L-valyl)-L-valyl)-L-tyrosyl)-L-prolyl)-L-tryptophyl)- Leucyl-valyl-valyl-tyrosyl-prolyl-tryptophyl-threonine Leu-val-val-tyr-pro-trp-thr (CAS 137201-62-8), a certified reference material (molecular formula C45H64N8O10, MW 877.04 g/mol) for analytical method development and quality control.

The molecular framework of 137201-62-8 Spinorphin L-Threonine, N-(N-(1-(N-(N-(N-L-leucyl-L-valyl)-L-valyl)-L-tyrosyl)-L-prolyl)-L-tryptophyl)- Leucyl-valyl-valyl-tyrosyl-prolyl-tryptophyl-threonine Leu-val-val-tyr-pro-trp-thr (C45H64N8O10) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
