Product Overview

4-Methylanisole 98.5% is a high-purity aromatic ether compound designed for demanding laboratory applications where precision and consistency are critical. This colorless to pale yellow liquid features a characteristic sweet, anise-like odor with a molecular formula of C8H10O and a molecular weight of 122.17 g/mol. The compound’s high assay purity (minimum 98.5%) ensures reliable results in organic synthesis reactions, particularly in Friedel-Crafts alkylations and aromatic substitutions. Its low moisture content (<0.1%) prevents unwanted side reactions in sensitive applications. The chemical's boiling point of 175-177°C and density of 0.975 g/mL at 25°C make it suitable for various separation techniques including distillation and chromatography. The product is stabilized to prevent oxidation during storage and comes in a high-density polyethylene bottle with a tamper-evident seal to maintain integrity. Each batch undergoes rigorous GC-MS analysis to verify purity and absence of common impurities like anisole or cresol derivatives.

FAQs

1. What is the shelf life of 4-Methylanisole 98.5% when stored properly?

When stored in its original sealed container at room temperature away from direct sunlight and moisture, the product maintains its specified purity for at least 24 months from the date of manufacture.

2. Can this product be used directly in GC-MS analysis without further purification?

The 98.5% purity level makes it suitable for most GC-MS applications, though some ultra-sensitive analyses may require additional filtration to remove potential particulate contaminants.

3. What safety precautions should be taken when handling this chemical?

Always use in a well-ventilated area or fume hood, wear appropriate PPE including nitrile gloves and safety goggles, and avoid skin contact as it may cause irritation.

4. How does this compare to lower purity grades available in the market?

This 98.5% grade contains significantly fewer impurities like anisole (typically <0.5%) compared to technical grades (85-90%), making it more reliable for quantitative analyses and synthesis reactions.

5. What is the recommended storage temperature for long-term stability?

For optimal stability, store between 15-25°C in a tightly sealed container, avoiding temperature fluctuations that could lead to condensation inside the bottle.
