Chemical Structure
Description
The occurrence of Dnp-Pro-Gln-Gly-OH 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.
Dnp-Pro-Gln-Gly-OH (CAS 65080-33-3) is a high-purity analytical reference standard with the molecular formula C18H22N6O9 and a molecular weight of 466.40 g/mol.
The molecular framework of Dnp-Pro-Gln-Gly-OH (C18H22N6O9) 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 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.
As a certified reference material (CRM), Dnp-Pro-Gln-Gly-OH meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
