Chemical Structure
Description
The occurrence of Halothane (1 mL) ((+/-)-2-Bromo-2-chloro-1,1,1-trifluoroethane) is closely related to fluorine/chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Halothane (1 mL) ((+/-)-2-Bromo-2-chloro-1,1,1-trifluoroethane) (CAS 151-67-7), molecular formula C2HBrClF3 and molecular weight 197.38 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C2HBrClF3, Halothane (1 mL) ((+/-)-2-Bromo-2-chloro-1,1,1-trifluoroethane) contains fluorine/chlorine/bromine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 197.38 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
