Chemical Structure
Description
As a certified reference material (CRM), MS-PEG1-THP 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.
MS-PEG1-THP (CAS 1309248-13-2), molecular formula C8H16O5S and molecular weight 224.27 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, MS-PEG1-THP is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 224.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
