Chemical Structure

Poly(D-lysine) CAS 26853-89-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 146.19 g/mol gives Poly(D-lysine) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Poly(D-lysine) (CAS 26853-89-4), molecular formula C6H14N2O2 and molecular weight 146.19 g/mol, is a CATO reference standard with documented purity and traceability.

Poly(D-lysine) (C6H14N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), Poly(D-lysine) 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.
