Chemical Structure

Benzyl-PEG5-Ms CAS 1807539-07-6 chemical structure

Description

CATO manufactures Benzyl-PEG5-Ms 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.

Benzyl-PEG5-Ms (CAS 1807539-07-6), molecular formula C18H30O8S and molecular weight 406.49 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Benzyl-PEG5-Ms (C18H30O8S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 406.49 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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