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.
1'H-spiro[cyclohexane-1,2'-quinoline] (CAS 25337-81-9), molecular formula C14H17N and molecular weight 199.29 g/mol, is a CATO reference standard with documented purity and traceability.
1'H-spiro[cyclohexane-1,2'-quinoline] (C14H17N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 1'H-spiro[cyclohexane-1,2'-quinoline] 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.
