Description

2-Ethyl-5-Methylthiazole CAS NO 19961-53-6 is a high-purity heterocyclic organic compound belonging to the thiazole family, valued for its potent and distinctive organoleptic properties. This chemical serves as a critical building block and flavor/fragrance ingredient, offering a powerful, nutty, and roasted character essential for creating complex sensory profiles. It is primarily sought after by manufacturers in the flavor and fragrance, food ingredient, and fine chemical synthesis industries for premium applications.

Application

• Flavor & Fragrance Industry: A key aroma chemical used to impart roasted, nutty, meaty, and cocoa-like notes in savory flavors, coffee, chocolate, and nut flavorings.
• Food Ingredient Manufacturing: Employed in the creation of reaction flavors and process flavorings for snacks, sauces, and ready-to-eat meals.
• Fine Chemical Synthesis: Acts as a versatile intermediate in the synthesis of more complex heterocyclic compounds for pharmaceutical and agrochemical research.
• Perfumery: Used in trace amounts to add depth and unique roasted nuances to high-end fragrance compositions.
• Research & Development: Serves as a standard or reagent in analytical chemistry and sensory science studies related to food chemistry.

Quality Control

Every batch of our 2-Ethyl-5-Methylthiazole is produced and tested under a strict quality management system to ensure consistency and purity for sensitive flavor and fragrance applications. We provide comprehensive Certificates of Analysis (COA) detailing purity, identity, and impurity profiles, typically determined via GC, GC-MS, and organoleptic assessment. Our quality commitment aligns with standards relevant to FEMA and IOFI guidelines for flavor ingredients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C/59-77°F). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in the original packaging or opaque storage until use.
