2272-45-9 4-Methyl-N-(phenylmethylene)benzenamine Benzylidene-p-tolyl-amine N-Benzylidene-4-methylaniline N-Benzylidene-p-toluidine CAS 2272-45-9

Description

2272-45-9 4-Methyl-N-(phenylmethylene)benzenamine Benzylidene-p-tolyl-amine N-Benzylidene-4-methylaniline N-Benzylidene-p-toluidine (CAS 2272-45-9), molecular formula C14H13N and molecular weight 195.26 g/mol, is a CATO reference standard with documented purity and traceability.

2272-45-9 4-Methyl-N-(phenylmethylene)benzenamine Benzylidene-p-tolyl-amine N-Benzylidene-4-methylaniline N-Benzylidene-p-toluidine (C14H13N) 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 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.

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.
