Chemical Structure

4-((1H-Inden-1-ylidene)methyl)-N,N-dimethylaniline CAS 443-30-1 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.

4-((1H-Inden-1-ylidene)methyl)-N,N-dimethylaniline (CAS 443-30-1), molecular formula C18H17N and molecular weight 247.33 g/mol, is a CATO reference standard with documented purity and traceability.

4-((1H-Inden-1-ylidene)methyl)-N,N-dimethylaniline (C18H17N) 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).

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.
