Description

2-Bromo-4,6-Dihydro-4-Methyl-5H-Thieno[2',3':4,5]Pyrrolo[2,3-D]Pyridazin-5-One is a high-value, heterocyclic organic building block of significant interest in advanced pharmaceutical research and development. Its complex fused-ring structure, incorporating thienopyrrolopyridazine and a bromine substituent, makes it a critical intermediate for synthesizing novel, biologically active compounds. This product is primarily targeted at medicinal chemists and process development scientists in the pharmaceutical, agrochemical, and fine chemical industries engaged in creating new drug candidates and specialty molecules.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of potential therapeutic agents, particularly in oncology and central nervous system (CNS) drug discovery programs.
• Medicinal Chemistry Scaffold: Used as a core structural motif for constructing compound libraries via parallel synthesis and structure-activity relationship (SAR) studies.
• Agrochemical Research: Employed in the development of new active ingredients for crop protection products, leveraging its heterocyclic framework.
• Chemical Biology Probe Synthesis: Utilized to create molecular tools for studying biological pathways and target validation.
• Fine Chemical Synthesis: Acts as a specialized building block for synthesizing complex organic molecules in custom manufacturing and contract research organizations (CROs).

Quality Control

Our 2-Bromo-4,6-Dihydro-4-Methyl-5H-Thieno[2',3':4,5]Pyrrolo[2,3-D]Pyridazin-5-One is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for research and development applications. Each lot undergoes rigorous analytical testing, including HPLC for purity and identity confirmation. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccants.
