Chemical Structure

Biotin-PEG4-Amine CAS 663171-32-2 chemical structure

Description

The molecular framework of Biotin-PEG4-Amine (C20H38N4O6S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Biotin-PEG4-Amine (CAS 663171-32-2) is a high-purity analytical reference standard with the molecular formula C20H38N4O6S and a molecular weight of 462.60 g/mol.

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

CATO manufactures Biotin-PEG4-Amine 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.
