Description

5-Bromo-Pentanal is a versatile and highly reactive bifunctional organic building block, essential for constructing complex molecular architectures. Its value lies in its ability to serve as a key electrophilic synthon, introducing both a bromoalkyl chain and an aldehyde functionality in a single step. This compound is critically needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for applications such as heterocyclic synthesis and the preparation of active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediates: A crucial precursor in the synthesis of various heterocyclic compounds, including pyrrolidines and piperidines, which are core structures in many active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the development of novel pesticides and herbicides, where its reactive handles allow for the construction of specific bioactive side chains.
• Ligand and Catalyst Development: Serves as a starting material for synthesizing specialized ligands for metal catalysis and organocatalysts.
• Polymer & Material Science: Employed as a monomer or cross-linking agent in the production of specialty polymers and functional materials.
• Chemical Biology Probes: Utilized in the synthesis of molecular probes and linkers for bioconjugation and protein labeling studies.
• Flavor & Fragrance Industry: Acts as an intermediate for the synthesis of certain aroma chemicals and fragrance components.

Quality Control

Every batch of our 5-Bromo-Pentanal is produced and tested under a strict quality management system to ensure consistency and reliability for your critical synthesis. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as purity, identity, and impurity profiles. Our quality commitment aligns with cGMP principles where applicable, supporting its use in regulated research and development.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C to minimize oxidation and degradation due to its highly volatile and easily oxidized nature. Keep away from heat, sparks, and open flame. Use in a well-ventilated area or fume hood.
