Description

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.

776-34-1 1-Naphthalenamine, 4-nitro- 1-Naphthylamine, 4-nitro- 4-Nitro-1-naphthylamine 4-12-00-03114 (Beilstein Handbook Reference) AI3-62662 1-Amino-4-nitronaphthalene BRN 2211897 EINECS 212-277-7 4-Nitro-1-naphthamine 1,4-Nitronaphthylamine 4-Nitro-alpha-naphthylamine NSC 614 (CAS 776-34-1) is a high-purity analytical reference standard with the molecular formula C10H18N2O2 and a molecular weight of 198.26 g/mol.

The molecular framework of 776-34-1 1-Naphthalenamine, 4-nitro- 1-Naphthylamine, 4-nitro- 4-Nitro-1-naphthylamine 4-12-00-03114 (Beilstein Handbook Reference) AI3-62662 1-Amino-4-nitronaphthalene BRN 2211897 EINECS 212-277-7 4-Nitro-1-naphthamine 1,4-Nitronaphthylamine 4-Nitro-alpha-naphthylamine NSC 614 (C10H18N2O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
