Chemical Identity and Properties
1-(4-Amino-3-methoxyphenyl)ethanone (SKU E728593) is a substituted acetophenone in which the para position of the phenyl ring carries a primary amine (–NH2) and the meta position carries a methoxy group (–OCH3). The molecular formula is C9H11NO2 and the molecular weight is approximately 165.19 g/mol.
The compound possesses three reactive sites that can participate independently or cooperatively in chemical transformations: (1) the amine group, susceptible to acylation, reductive alkylation, diazotization, and condensation reactions; (2) the carbonyl of the acetyl group, available for nucleophilic addition, Baeyer–Villiger oxidation, or condensation; and (3) the methoxy group, which can be demethylated under harsh acidic or Lewis-acid conditions to expose a free phenol.
Physical properties such as exact melting point, boiling point, density, and purity specification should be confirmed against the Certificate of Analysis (CoA) supplied with each lot of E728593, as these values may vary between batches.
Safe Handling, Storage, and Waste Disposal
Personal Protective Equipment (PPE): Wear chemical-splash goggles, a lab coat, and nitrile gloves when handling this compound. Aromatic amines as a chemical class carry potential health hazards; minimize skin contact and inhalation of dust or vapors. Work in a well-ventilated laboratory or fume hood.
Storage: Store E728593 in a tightly sealed container, away from heat, ignition sources, and strong oxidizing agents. A cool, dry location (typically 2–8 °C or room temperature as specified on the product label) is recommended. Keep separate from food and feed products. Confirm specific storage temperature on the product label or CoA.
Spill Management: Contain small spills with inert absorbent material (e.g., vermiculite or dry sand). Transfer to a labeled waste container. Avoid generating dust. Clean the area with water.
Waste Disposal: Dispose of this compound and contaminated materials in accordance with local, regional, and national regulations governing hazardous chemical waste. Do not discharge to drains or waterways. Consult your institution's Environmental Health and Safety (EHS) office for guidance.
Note: Always consult the Safety Data Sheet (SDS) for E728593 before first use. SDS information supersedes any general guidance provided here.
Applications in Organic and Medicinal Chemistry
The bifunctional nature of 1-(4-Amino-3-methoxyphenyl)ethanone makes it a valuable building block in multiple synthetic contexts:
- Pharmaceutical intermediates: The free amine can be selectively acylated or coupled with activated carboxylic acids to form amides, which are common pharmacophores in drug candidates. The adjacent methoxy group can influence ring electronics and modulate the binding affinity of resulting compounds.
- Heterocyclic synthesis: The amine and ketone functionalities can cooperate in forming nitrogen-containing heterocycles such as benzimidazoles, quinoxalines, and related scaffolds upon reaction with appropriate bifunctional partners (e.g., 1,2-diketones, o-phenylenediamines).
- Dye and pigment chemistry: Aminoacetophenone derivatives are established intermediates in azo dye synthesis via diazotization of the amine followed by azo coupling.
- Material science research: Methoxy-substituted aromatic ketones have been explored as photoinitiators and as monomers for functional polymer synthesis.
Researchers should optimize reaction conditions (solvent, temperature, protecting-group strategy) empirically for each target transformation, as the reactivity balance between the amine and the ketone will depend strongly on the reagents employed.

Frequently asked questions
What is the molecular formula and molecular weight of 1-(4-Amino-3-methoxyphenyl)ethanone?
The molecular formula is C9H11NO2 and the molecular weight is approximately 165.19 g/mol. Always confirm exact values against the Certificate of Analysis provided with your specific lot of E728593.
How should 1-(4-Amino-3-methoxyphenyl)ethanone (E728593) be stored to maintain stability?
Store the compound in a tightly sealed container in a cool, dry place away from heat, light, moisture, and strong oxidizing agents. The specific recommended storage temperature is indicated on the product label and CoA; confirm this before use. Exposure of the amine group to air and moisture over extended periods may lead to degradation.
Which types of chemical reactions can the amine group of this compound undergo?
The primary aromatic amine can participate in acylation to form amides, reductive alkylation to form secondary or tertiary amines, diazotization followed by azo coupling for dye synthesis, and condensation reactions with carbonyl compounds to form imines or related heterocycles. Selectivity relative to the ketone carbonyl must be managed through appropriate reaction conditions and, where necessary, temporary protection of one functional group.
Is 1-(4-Amino-3-methoxyphenyl)ethanone hazardous, and what PPE is required?
As an aromatic amine derivative, this compound should be handled with appropriate caution. Wear chemical-splash goggles, a lab coat, and nitrile gloves, and work in a well-ventilated area or fume hood to avoid inhalation of dust or vapors. Consult the Safety Data Sheet (SDS) for E728593 for complete hazard classification and first-aid measures before handling.
How can I order E728593 from Aladdin Scientific, and what documentation is available?
E728593 can be ordered directly through the Aladdin Scientific website or by contacting your regional sales representative. A Certificate of Analysis (CoA) and Safety Data Sheet (SDS) are available for each lot. For bulk orders, custom specifications, or export documentation, please contact Aladdin's customer service team directly.
