Chemical Structure

MS-PEG4-t-butyl ester CAS 1024602-74-1 chemical structure

Description

MS-PEG4-t-butyl ester (CAS 1024602-74-1), molecular formula C14H28O8S and molecular weight 356.43 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-PEG4-t-butyl ester is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 356.43 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.

As a certified reference material (CRM), MS-PEG4-t-butyl ester 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.
