Description
CATO supplies Propargyl-PEG4-S-PEG4-acid (CAS 2055041-20-6), a certified reference material (molecular formula C22H40O10S, MW 496.61 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, Propargyl-PEG4-S-PEG4-acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 496.61 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.
CATO manufactures Propargyl-PEG4-S-PEG4-acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
