Chemical Structure

Biotin-PEG5-NH-Boc CAS 189209-28-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 606.77 g/mol gives Biotin-PEG5-NH-Boc distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Biotin-PEG5-NH-Boc (CAS 189209-28-7), molecular formula C27H50N4O9S and molecular weight 606.77 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Biotin-PEG5-NH-Boc (C27H50N4O9S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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).

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), Biotin-PEG5-NH-Boc 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.
