Chemical Structure
Description
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.
Rel-(1R,2R,4R)-bicyclo[2.2.1]hept-5-ene-2-carbonitrile (CAS 2888-90-6), molecular formula C8H9N and molecular weight 119.16 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Rel-(1R,2R,4R)-bicyclo[2.2.1]hept-5-ene-2-carbonitrile (C8H9N) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), Rel-(1R,2R,4R)-bicyclo[2.2.1]hept-5-ene-2-carbonitrile 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.
