Chemical Structure

Boc-NH-PEG5-propargyl CAS 2062663-67-4 chemical structure

Description

Boc-NH-PEG5-propargyl (CAS 2062663-67-4), molecular formula C18H33NO7 and molecular weight 375.46 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, Boc-NH-PEG5-propargyl is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 375.46 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).

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), Boc-NH-PEG5-propargyl 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.
