Chemical Structure

m-PEG12-Br CAS 1620461-89-3 chemical structure

Description

m-PEG12-Br (CAS 1620461-89-3), molecular formula C25H51BrO12 and molecular weight 623.57 g/mol, is a CATO reference standard with documented purity and traceability.

m-PEG12-Br (C25H51BrO12) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), m-PEG12-Br 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.
