Chemical Structure
Description
The occurrence of Acetyl tetrapeptide-9(Dermican LS 9837) is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Acetyl tetrapeptide-9(Dermican LS 9837) (CAS 928006-50-2), a certified reference material (molecular formula C22H33N7O9, MW 539.54 g/mol) for analytical method development and quality control.
The molecular framework of Acetyl tetrapeptide-9(Dermican LS 9837) (C22H33N7O9) is characterized by a flavonoid core, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
