Description

643-28-7 Aniline, o-isopropyl- Benzenamine, 2-(1-methylethyl)- 2-Isopropylaniline 4-12-00-02630 (Beilstein Handbook Reference) o-Aminoisopropylbenzene 2-Aminoisopropylbenzene BRN 0636283 o-Cumidine EINECS 211-397-7 2-Isopropyl aniline o-Isopropylaniline 2-(1-Methylethyl)benzenamine (CAS 643-28-7) is a high-purity analytical reference standard with the molecular formula C9H19N and a molecular weight of 141.25 g/mol.

643-28-7 Aniline, o-isopropyl- Benzenamine, 2-(1-methylethyl)- 2-Isopropylaniline 4-12-00-02630 (Beilstein Handbook Reference) o-Aminoisopropylbenzene 2-Aminoisopropylbenzene BRN 0636283 o-Cumidine EINECS 211-397-7 2-Isopropyl aniline o-Isopropylaniline 2-(1-Methylethyl)benzenamine (C9H19N) contains an organic framework. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
