Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 802.00 g/mol gives N-(Hydroxy-PEG3)-N-bis(PEG4-Boc) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies N-(Hydroxy-PEG3)-N-bis(PEG4-Boc) (CAS 2112734-70-8), a certified reference material (molecular formula C38H75NO16, MW 802.00 g/mol) for analytical method development and quality control.
The molecular framework of N-(Hydroxy-PEG3)-N-bis(PEG4-Boc) (C38H75NO16) is characterized by an amide group, a carboxylic acid 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), N-(Hydroxy-PEG3)-N-bis(PEG4-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.
