Overview
1-Methylindole is an organic compound belonging to the indole family, characterized by a benzene ring fused to a pyrrole ring. It is widely used in the chemical industry due to its versatile reactivity and aromatic properties. The compound is typically synthesized through methylation of indole or via other organic reactions. It serves as a key intermediate in the production of various specialty chemicals. In industrial settings, 1-methylindole is valued for its role in synthesizing pharmaceuticals, where it acts as a precursor for active pharmaceutical ingredients (APIs). Its aromatic nature also makes it useful in the fragrance industry, where it contributes to complex scent profiles.
Physical and Chemical Properties
1-Methylindole is a colorless to pale yellow liquid with a distinct aromatic odor. It has a molecular weight of 131.17 g/mol and a density of 1.07 g/cm³. The compound boils at 234-236 °C and is soluble in common organic solvents like ethanol and ether, though it has limited solubility in water. Chemically, 1-methylindole is stable under normal conditions but can react with strong oxidizing agents. Its reactivity is influenced by the electron-rich indole ring, making it a useful building block for further chemical modifications. The compound's volatility requires careful handling to avoid inhalation or skin contact.
Main Applications
1-Methylindole is primarily used in the pharmaceutical industry as an intermediate for synthesizing APIs and other bioactive molecules. Its structural features make it a valuable precursor for drugs targeting neurological and anti-inflammatory conditions. In the fragrance industry, 1-methylindole is employed to create complex floral and musky scents. It is also used in agrochemicals, where it serves as a building block for pesticides and herbicides. Additionally, researchers utilize it in organic chemistry studies to explore new synthetic pathways.
Safety and Storage
1-Methylindole is classified as an irritant, posing risks to skin, eyes, and respiratory systems. Proper personal protective equipment (PPE), including gloves and goggles, should be worn when handling the compound. Adequate ventilation is essential to prevent inhalation of vapors. Storage conditions should include a cool, dry, and well-ventilated area, away from heat sources and open flames. The compound should be kept in tightly sealed containers to minimize exposure to air and moisture. Spills should be contained and cleaned up promptly using appropriate absorbent materials.
B2B Procurement Guide
When procuring 1-methylindole, B2B buyers should prioritize suppliers with verified CAS numbers and certificates of analysis (CoA) to ensure product purity. Bulk purchases often come with cost advantages, but buyers should confirm lead times and shipping conditions to avoid delays. Quality control is critical; buyers should request samples for testing before large-scale orders. Pricing varies based on purity and supplier, with typical ranges between $50-$100 per kilogram. Long-term contracts may offer additional discounts, but flexibility in sourcing is recommended to mitigate supply chain disruptions.
