Lysine Impurity 16 CAS 4272-71-3

Description

Compared with other compounds in its class, the molecular weight of 401.41 g/mol gives Lysine Impurity 16 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Lysine Impurity 16 (CAS 4272-71-3) is a high-purity analytical reference standard with the molecular formula C20H23N3O6 and a molecular weight of 401.41 g/mol.

The molecular framework of Lysine Impurity 16 (C20H23N3O6) 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).

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.

As a certified reference material (CRM), Lysine Impurity 16 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.
