Methoxybenzaldehyde

Updated: 2026-09-16

Overview

Methoxybenzaldehyde, commonly known as anisaldehyde, is an aromatic organic compound with a distinctive sweet, floral odor. It is derived from benzaldehyde by the introduction of a methoxy group. This compound is widely utilized in the fragrance and flavor industry due to its pleasant aroma, resembling anise or vanilla. As a versatile intermediate, methoxybenzaldehyde plays a crucial role in the synthesis of pharmaceuticals, agrochemicals, and other fine chemicals. Its stability and reactivity make it a valuable building block in organic chemistry, particularly in the production of dyes and perfumes.

Physical and Chemical Properties

Methoxybenzaldehyde is a colorless to pale yellow liquid at room temperature, with a molecular weight of 136.15 g/mol. It has a density of 1.119 g/cm³ and a boiling point of 248°C. The compound is soluble in organic solvents like ethanol and ether but has limited solubility in water. Its key chemical properties include volatility and flammability, requiring careful handling. The presence of the methoxy group enhances its electron-donating characteristics, making it reactive in electrophilic aromatic substitution reactions. These properties are critical for its applications in synthetic chemistry.

Main Applications

Methoxybenzaldehyde is primarily used as a flavoring agent in food products, imparting a sweet, anise-like taste. It is also a popular ingredient in perfumes and cosmetics, where its floral aroma is highly valued. In the pharmaceutical industry, it serves as an intermediate for synthesizing drugs such as antihypertensives and antipyretics. Additionally, it is employed in the production of agrochemicals and dyes. Its role as a precursor in organic synthesis underscores its importance in industrial chemistry, particularly in the manufacture of fine chemicals and specialty materials.

Safety and Storage

Methoxybenzaldehyde is classified as an irritant, posing risks to skin and eyes upon contact. Proper personal protective equipment (PPE), including gloves and goggles, is essential when handling this compound. Inhalation of vapors should be avoided, and adequate ventilation is necessary in workplaces. Storage conditions require a cool, dry, and well-ventilated area, away from heat sources and open flames. The compound should be kept in tightly sealed containers to prevent evaporation and contamination. Compliance with safety regulations is crucial to minimize risks during transport and usage.

B2B Procurement Guide

When procuring methoxybenzaldehyde, industrial buyers should prioritize suppliers with verified certifications, such as ISO or GMP, to ensure product quality and consistency. Key specifications to confirm include CAS number (123-11-5), purity levels (typically 98-99%), and packaging options. Price negotiations should consider bulk purchase discounts, with reference prices ranging from $20 to $50 per kilogram. Logistics planning should account for the compound's flammability, requiring secure and compliant transportation methods. Establishing long-term supplier relationships can enhance reliability and cost efficiency.
