Description

2-Bromo-2-Methylpropane (CAS NO 507-19-7), also known as tert-Butyl bromide, is a versatile and highly reactive alkyl halide. Its value lies in its role as a key alkylating agent and a fundamental building block for synthesizing more complex organic molecules. This compound is essential for research and production in the pharmaceutical, agrochemical, and specialty chemical industries, where it is used to introduce the tert-butyl group into target compounds.

Application

• Pharmaceutical Intermediate: A crucial reagent for the synthesis of active pharmaceutical ingredients (APIs), particularly in creating compounds with tert-butyl substituents to modify solubility and metabolic stability.
• Agrochemical Synthesis: Used in the manufacture of pesticides, herbicides, and fungicides as an alkylating agent to build specific molecular frameworks.
• Organic Synthesis Reagent: Serves as a fundamental starting material or intermediate in various organic reactions, including nucleophilic substitutions and Grignard reagent preparations.
• Polymer & Material Science: Employed as an initiator or chain transfer agent in certain polymerization processes and in the synthesis of specialty polymers.
• Laboratory Research: A standard reagent in academic and industrial R&D labs for method development and exploratory chemistry.
• Flavor & Fragrance Ingredient Synthesis: Used in the production pathway for certain aroma chemicals and flavor compounds.

Quality Control

Our 2-Bromo-2-Methylpropane is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including GC analysis for purity and identity verification, to ensure it meets the high standards required for industrial and research applications. Certificates of Analysis (COA) documenting purity, assay, and impurity profiles are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use. Recommended storage temperature is 2-8°C for extended stability, though short-term storage at controlled room temperature (15-25°C) is acceptable.
