Chemical Structure
Description
The occurrence of 2-bromo-1,1-difluoroethane is closely related to fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-bromo-1,1-difluoroethane (CAS 359-07-9), molecular formula C2H3BrF2 and molecular weight 144.95 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-bromo-1,1-difluoroethane (C2H3BrF2) contains fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 144.95 g/mol, it falls into the low-molecular-weight range. 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), 2-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.
