Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
CATO supplies 5,6,7,8-tetrahydronaphthalene-1,4-diamine (CAS 861331-69-3), a certified reference material (molecular formula C10H14N2, MW 162.23 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 5,6,7,8-tetrahydronaphthalene-1,4-diamine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 162.23 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.
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.
