Chemical Structure
Description
6,7,8-Trimethyl-1,2,3,4-tetrahydro-1,5-naphthyridine (CAS 1555951-85-3) is a high-purity analytical reference standard with the molecular formula C11H16N2 and a molecular weight of 176.26 g/mol.
The molecular framework of 6,7,8-Trimethyl-1,2,3,4-tetrahydro-1,5-naphthyridine (C11H16N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 6,7,8-Trimethyl-1,2,3,4-tetrahydro-1,5-naphthyridine 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.
