Chemical Structure
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 Propargyl-PEG4-CH2-methyl ester (CAS 1872433-63-0), a certified reference material (molecular formula C14H24O6, MW 288.34 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Propargyl-PEG4-CH2-methyl ester is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 288.34 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).
As a certified reference material (CRM), Propargyl-PEG4-CH2-methyl 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.
