Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,2-Dibromo-1-chloro-1-fluoroethane.
1,2-Dibromo-1-chloro-1-fluoroethane (CAS 243139-69-7), molecular formula C2H2Br2ClF and molecular weight 240.30 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C2H2Br2ClF, 1,2-Dibromo-1-chloro-1-fluoroethane contains fluorine/chlorine/bromine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 240.30 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.
