Description

Urea, N-[4-[1-[(2,6-difluorophenyl)methyl]-5-[(dimethyloxidoamino)methyl]-1,2,3,4-tetrahydro-3-(6-methoxy-3-pyridazinyl)-2,4-dioxothieno[2,3-d]pyrimidin-6-yl]phenyl]-N'-methoxy- is a sophisticated heterocyclic urea derivative designed for advanced pharmaceutical research and development. This compound matters as a key pharmacological intermediate or active pharmaceutical ingredient (API) precursor, offering a complex molecular scaffold for targeting specific biological pathways. It is primarily needed by pharmaceutical companies and biotech research organizations engaged in the discovery and synthesis of novel therapeutic agents.

Application

• Pharmaceutical Intermediate: Serves as a critical building block in the multi-step synthesis of novel drug candidates, particularly in oncology and targeted therapies.
• Biochemical Research: Used as a reference standard or probe in enzymatic and receptor binding assays to study structure-activity relationships (SAR).
• Preclinical Development: Employed in the formulation and testing of new chemical entities (NCEs) during early-stage drug development.
• Medicinal Chemistry: Provides a complex core structure for the design and optimization of molecules with potential kinase inhibitory or other targeted activities.
• Contract Research & Manufacturing (CRO/CMO): Supplied to organizations specializing in custom synthesis and process development for the pharmaceutical industry.

Quality Control

Our high-value pharmaceutical intermediates are produced under strict quality management systems. Each batch undergoes comprehensive analytical characterization using techniques such as HPLC, NMR, and LC-MS to confirm identity and purity. A detailed Certificate of Analysis (COA) is provided with every shipment, ensuring full traceability and compliance with research-grade specifications. We support development with custom purity grades and analytical method support upon request.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) or as indicated on the label or COA. This material is moisture-sensitive (hygroscopic) and should be handled under anhydrous conditions when necessary. Keep container tightly sealed in a dry and well-ventilated place.
