Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 259.24 g/mol gives m-PEGn-NHS ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
m-PEGn-NHS ester (CAS 174569-25-6) is a high-purity analytical reference standard with the molecular formula C10H15NO6N and a molecular weight of 259.24 g/mol.
m-PEGn-NHS ester (C10H15NO6N) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), m-PEGn-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.
