Chemical Structure
Description
Propargyl-PEG1-SS-PEG1-acid (CAS 1807503-85-0) is a high-purity analytical reference standard with the molecular formula C10H16O4S2 and a molecular weight of 264.36 g/mol.
Based on its molecular formula C10H16O4S2, Propargyl-PEG1-SS-PEG1-acid contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 264.36 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-PEG1-SS-PEG1-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.
