Chemical Structure
Description
CATO supplies Mal-PEG1-Val-Cit-PABC-OH (CAS 2055041-37-5), a certified reference material (molecular formula C27H38N6O8, MW 574.63 g/mol) for analytical method development and quality control.
Mal-PEG1-Val-Cit-PABC-OH (C27H38N6O8) contains a nitrogen-containing heterocyclic scaffold, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), Mal-PEG1-Val-Cit-PABC-OH 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.
