Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including B28ZGH99IH 552-82-9 Methyldiphenylamine Benzenamine, N-methyl-N-phenyl- Diphenylamine, N-methyl- (8CI) AI3-02479 Diphenylmethylamine N,N-Diphenylmethylamine EINECS 209-023-2 N-Methyldiphenylamine N-Methyl-N-phenylaniline NSC 3790 UNII-B28ZGH99IH.

B28ZGH99IH 552-82-9 Methyldiphenylamine Benzenamine, N-methyl-N-phenyl- Diphenylamine, N-methyl- (8CI) AI3-02479 Diphenylmethylamine N,N-Diphenylmethylamine EINECS 209-023-2 N-Methyldiphenylamine N-Methyl-N-phenylaniline NSC 3790 UNII-B28ZGH99IH (CAS 552-82-9), molecular formula C13H25N and molecular weight 195.34 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, B28ZGH99IH 552-82-9 Methyldiphenylamine Benzenamine, N-methyl-N-phenyl- Diphenylamine, N-methyl- (8CI) AI3-02479 Diphenylmethylamine N,N-Diphenylmethylamine EINECS 209-023-2 N-Methyldiphenylamine N-Methyl-N-phenylaniline NSC 3790 UNII-B28ZGH99IH is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 195.34 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.

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.
