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.
PRopargyl-peg6-tos (CAS 1422023-55-9), molecular formula C20H30O8S and molecular weight 430.51 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, PRopargyl-peg6-tos is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 430.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures PRopargyl-peg6-tos 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.
