4-Amino-3-Methylphenol CAS 2835-99-6 chemical structure

Description

CATO supplies 4-Amino-3-Methylphenol (CAS 2835-99-6), a certified reference material (molecular formula C7H9NO, MW 123.15 g/mol) for analytical method development and quality control.

Based on its molecular formula C7H9NO, 4-Amino-3-Methylphenol contains an amide group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 123.15 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
