Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 6-(Tert-butyl)-3-chloro-5,6,7,8-tetrahydrocinnoline is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 224.73 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
6-(Tert-butyl)-3-chloro-5,6,7,8-tetrahydrocinnoline (CAS 39715-71-4) is a high-purity analytical reference standard with the molecular formula C12H17ClN2 and a molecular weight of 224.73 g/mol.
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), 6-(Tert-butyl)-3-chloro-5,6,7,8-tetrahydrocinnoline 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.
