Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 86917-56-8 Substance P (4-11), pro(4)-val(8)-trp(7,9,10)- 4-Prolyl-8-valyl-7,9,10-tryptophan-substance P (4-11) 4-Pro-8-val-7,9,10-trp-substance P (4-11) Pvt-SP(4-11) Substance P (4-11), prolyl(4)-valyl(8)-tryptophan(7,9,10)-.

CATO supplies 86917-56-8 Substance P (4-11), pro(4)-val(8)-trp(7,9,10)- 4-Prolyl-8-valyl-7,9,10-tryptophan-substance P (4-11) 4-Pro-8-val-7,9,10-trp-substance P (4-11) Pvt-SP(4-11) Substance P (4-11), prolyl(4)-valyl(8)-tryptophan(7,9,10)- (CAS 86917-56-8), a certified reference material (molecular formula C58H74N14O10S, MW 1159.36 g/mol) for analytical method development and quality control.

Structurally, 86917-56-8 Substance P (4-11), pro(4)-val(8)-trp(7,9,10)- 4-Prolyl-8-valyl-7,9,10-tryptophan-substance P (4-11) 4-Pro-8-val-7,9,10-trp-substance P (4-11) Pvt-SP(4-11) Substance P (4-11), prolyl(4)-valyl(8)-tryptophan(7,9,10)- (C58H74N14O10S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 29.0, corresponding to approximately 29 ring(s) or double-bond equivalent(s). With a molecular weight of 1159.36 g/mol, it falls into the high-molecular-weight range. 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.

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.
