Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-Ethynyl-4-fluorobicyclo[2.2.1]heptane (CAS 2287310-81-8), molecular formula C9H11F and molecular weight 138.18 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Ethynyl-4-fluorobicyclo[2.2.1]heptane (C9H11F) is characterized by fluorine substitution, an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 1-Ethynyl-4-fluorobicyclo[2.2.1]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.
