Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 316.39 g/mol gives Propargyl-PEG4-Boc distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Propargyl-PEG4-Boc (CAS 1355197-66-8), a certified reference material (molecular formula C16H28O6, MW 316.39 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Propargyl-PEG4-Boc is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 316.39 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-Boc 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.
