Chemical Structure
Description
Propargyl-PEG3-SH (CAS 1412905-18-0) is a high-purity analytical reference standard with the molecular formula C9H16O3S and a molecular weight of 204.29 g/mol.
The molecular framework of Propargyl-PEG3-SH (C9H16O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Propargyl-PEG3-SH 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.
