Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies mPEG-Succinimidyl Carboxy Methyl ester) Mn 5,000 (CAS 92451-01-9), a certified reference material (molecular formula C8H11NO6C3H8O2, MW 293.27 g/mol) for analytical method development and quality control.
mPEG-Succinimidyl Carboxy Methyl ester) Mn 5,000 (C8H11NO6C3H8O2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), mPEG-Succinimidyl Carboxy Methyl ester) Mn 5,000 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.
