Chemical Structure

Diketone-PEG4-Biotin CAS 2353409-85-3 chemical structure

Description

The occurrence of Diketone-PEG4-Biotin is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Diketone-PEG4-Biotin (CAS 2353409-85-3), molecular formula C33H50N4O9S and molecular weight 678.84 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C33H50N4O9S, Diketone-PEG4-Biotin contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 678.84 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Diketone-PEG4-Biotin 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.
