Chemical Structure
Description
As a certified reference material (CRM), 6-bromo-2,2-difluoro-spiro[3.3]heptane 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.
6-bromo-2,2-difluoro-spiro[3.3]heptane (CAS 2260937-26-4), molecular formula C7H9BrF2 and molecular weight 211.05 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-bromo-2,2-difluoro-spiro[3.3]heptane (C7H9BrF2) is characterized by fluorine/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.
