Chemical Structure

Thiol-PEG4-Boc CAS 564476-33-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Thiol-PEG4-Boc.

Thiol-PEG4-Boc (CAS 564476-33-1), molecular formula C15H30O6S and molecular weight 338.46 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C15H30O6S, Thiol-PEG4-Boc contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 338.46 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
