Difelikefalin Impurity 19 is a difelikefalin-related peptide used to profile side products and decomposition pathways. Its sequence deviates subtly from the main active backbone, altering polarity and conformational preferences. Researchers use it to challenge analytical resolution and structural-assignment robustness. Applications include stability-indicating method development, impurity mapping, and structure-property investigation.
CAT No: Z10-101-200
Synonyms/Alias:1-(L-leucyl-L-lysyl)-4-aminopiperidine-4-carboxylic acid
