Chemical Structure
Description
The occurrence of 1-Bromo-2-Chloroethane is closely related to chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Bromo-2-Chloroethane (CAS 107-04-0), molecular formula C2H4BrCl and molecular weight 143.41 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-Bromo-2-Chloroethane (C2H4BrCl) contains chlorine/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 143.41 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), 1-Bromo-2-Chloroethane 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.
