Description

[1]Benzothieno[2,3-D]Pyrimidine, 2-Ethyl-5,6,7,8-Tetrahydro-4-(1-Piperazinyl)- (9Ci) is a high-purity, heterocyclic organic compound of significant interest in advanced chemical synthesis. This molecule serves as a critical pharmacological intermediate and building block for the development of novel active compounds. It is primarily required by pharmaceutical R&D teams and fine chemical manufacturers engaged in creating new therapeutic agents.

Application

• Pharmaceutical Intermediate: A key synthetic precursor in the research and development of new drug candidates, particularly for central nervous system (CNS) and oncology targets.
• Chemical Biology Research: Used as a core scaffold or probe in medicinal chemistry for structure-activity relationship (SAR) studies and hit-to-lead optimization.
• Active Pharmaceutical Ingredient (API) Synthesis: Employed in the multi-step synthesis of complex, biologically active molecules for preclinical and clinical studies.
• Academic & Contract Research: Serves as a valuable reagent for universities and CROs (Contract Research Organizations) exploring novel heterocyclic chemistry and its applications.
• Fine Chemical Production: Utilized in the manufacture of specialty chemicals where a functionalized benzothienopyrimidine core is required.

Quality Control

Every batch of this advanced intermediate is produced under strict quality management systems. We employ advanced analytical techniques including HPLC, GC, NMR, and MS to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support 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 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.
