Chemical Structure
Description
The occurrence of 1-Bromo-1-propene (cis- and trans- mixture) is closely related to bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Bromo-1-propene (cis- and trans- mixture) (CAS 590-14-7), molecular formula C3H5Br and molecular weight 120.98 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Bromo-1-propene (cis- and trans- mixture) (C3H5Br) is characterized by bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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-propene (cis- and trans- mixture) 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.
