Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, N-Biotin-N-bis(PEG4-acid) is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 739.87 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies N-Biotin-N-bis(PEG4-acid) (CAS 1964503-35-2), a certified reference material (molecular formula C32H57N3O14S, MW 739.87 g/mol) for analytical method development and quality control.
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), N-Biotin-N-bis(PEG4-acid) 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.
