Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including endo-BCN-PEG3-NHS ester.
endo-BCN-PEG3-NHS ester (CAS 2101206-94-2) is a high-purity analytical reference standard with the molecular formula C24H34N2O9 and a molecular weight of 494.53 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, endo-BCN-PEG3-NHS ester is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 494.53 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).
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), endo-BCN-PEG3-NHS ester 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.
