Chemical Structure

1-Bromo-1,1-difluoroethane CAS 420-43-9 chemical structure

Description

The occurrence of 1-Bromo-1,1-difluoroethane is closely related to fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-Bromo-1,1-difluoroethane (CAS 420-43-9) is a high-purity analytical reference standard with the molecular formula C2H3BrF2 and a molecular weight of 144.95 g/mol.

1-Bromo-1,1-difluoroethane (C2H3BrF2) contains fluorine/bromine substitution. Halogen substitution raises its density and boiling point; 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.

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), 1-Bromo-1,1-difluoroethane 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.
