5-ethyl-2-methylpyridine
Description
5-Ethyl-2-methylpyridine (CAS 104-90-5), commercially known as 5-ethyl-2-picoline or MEP, is a pyridine-base intermediate used as a building block in the synthesis of vitamins, agrochemicals, and pharmaceutical compounds.
It also carries FEMA 3546 status, recognizing its role as a flavoring agent in food applications. MEP is a primary raw material in the industrial production of nicotinic acid and nicotinamide.
In these processes, it undergoes catalytic oxidation at scale. In agrochemical manufacturing, it serves as a precursor to active ingredients in herbicide and pesticide formulations for global distribution.
Food and beverage producers use it as a flavoring agent to impart roasted, nutty, or popcorn-like notes in processed products at permitted use levels. It is highly valued for its specific profile.
Fragrance formulators incorporate it into compositions targeting savory or tobacco-adjacent scent profiles. 5-Ethyl-2-picoline is supplied as a liquid, typically in drums or ISO tank containers for bulk orders.
Technical grade is the standard commercial specification, with purity levels commonly at 98% or higher by GC. Food-grade material meeting FEMA compliance is available for flavor and fragrance applications.
These materials are produced to meet rigorous quality standards for industrial use. Our logistics network ensures that all shipments of this intermediate arrive safely and meet your specific production requirements.
