Description

Phenylbromoacetate CAS NO 670-72-4 is a versatile organic bromoester compound widely utilized as a key synthetic intermediate in advanced chemical manufacturing. Its primary value lies in its reactive bromomethyl group, which facilitates efficient carbon-carbon bond formation and functional group transformations under mild conditions. This makes it an essential building block for researchers and production chemists in the pharmaceutical, agrochemical, and specialty chemical industries seeking to develop novel active ingredients and complex molecular architectures.

Application

• Pharmaceutical Intermediate: Critical for the synthesis of various active pharmaceutical ingredients (APIs), particularly in constructing ester and ether linkages or introducing bromomethyl functionalities.
• Agrochemical Synthesis: Serves as a precursor in the manufacture of herbicides, fungicides, and plant growth regulators requiring specific brominated ester motifs.
• Organic Synthesis Reagent: Employed in classic reactions like the Reformatsky reaction and as an alkylating agent for nucleophilic substitution in research and development.
• Liquid Crystal & Polymer Chemistry: Used in the production of monomers and intermediates for specialty polymers and liquid crystal displays (LCDs).
• Dye & Pigment Manufacturing: Acts as an intermediate in the synthesis of complex organic dyes and colorants.
• Cross-Coupling Reactions: A valuable substrate in palladium-catalyzed cross-coupling reactions (e.g., Suzuki, Heck) for creating biaryl structures.

Quality Control

Our Phenylbromoacetate is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive quality assurance, with specifications typically meeting or exceeding standard reagent-grade requirements. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available for every batch upon request, supporting your regulatory and R&D documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture. Keep away from strong acids and incompatible materials.
