Chemical Structure
Description
The molecular framework of 2-Ethynylbicyclo[2.2.1]heptane (C9H12) is characterized by an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its non-polar molecular character, 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).
CATO supplies 2-Ethynylbicyclo[2.2.1]heptane (CAS 942577-24-4), a certified reference material (molecular formula C9H12, MW 120.19 g/mol) for analytical method development and quality control.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 2-Ethynylbicyclo[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.
