Chemical Structure

Br-PEG3-C2-Boc CAS 782475-37-0 chemical structure

Description

Br-PEG3-C2-Boc (CAS 782475-37-0), molecular formula C13H25BrO5 and molecular weight 341.24 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Br-PEG3-C2-Boc (C13H25BrO5) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), Br-PEG3-C2-Boc 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.
