Chemical Structure
Description
The occurrence of TCO-PEG6-NHS ester is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
TCO-PEG6-NHS ester (CAS 2353409-96-6), molecular formula C28H46N2O12 and molecular weight 602.67 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C28H46N2O12, TCO-PEG6-NHS ester contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 602.67 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), TCO-PEG6-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.
