Chemical Structure

Bis-Mal-Lysine-PEG4-acid CAS 1426164-52-4 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Bis-Mal-Lysine-PEG4-acid is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 695.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

Bis-Mal-Lysine-PEG4-acid (CAS 1426164-52-4) is a high-purity analytical reference standard with the molecular formula C31H45N5O13 and a molecular weight of 695.71 g/mol.

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), Bis-Mal-Lysine-PEG4-acid 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.
