Description

Tazasubrate is a specialized organic compound used primarily as a high-purity intermediate in pharmaceutical synthesis and advanced materials research. Its structural stability under controlled conditions enables precise regioselective reactions critical for active pharmaceutical ingredient (API) development. Global pharmaceutical R&D labs, contract development and manufacturing organizations (CDMOs), and specialty chemical manufacturers rely on Tazasubrate CAS NO 79071-15-1 for consistent batch performance in multi-step syntheses requiring stringent impurity control.

Application

• Key synthetic intermediate in the production of antithrombotic and anticoagulant drug candidates
• Building block for heterocyclic compounds in oncology-targeted small-molecule therapeutics
• Reagent in asymmetric catalysis for chiral scaffold construction
• Functional component in photoactive polymer precursors for OLED and photovoltaic material development
• Stabilized precursor in controlled-release prodrug formulations
• Reference standard in LC-MS and NMR method validation for regulatory submissions (FDA, EMA)
• Research-grade material for structure–activity relationship (SAR) studies in medicinal chemistry

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request. All batches conform to ISO 9001:2015 certified manufacturing protocols and meet ICH Q7 guidelines for pharmaceutical intermediates. Testing includes identity confirmation (IR, HPLC), assay (HPLC), residual solvents (GC), heavy metals (ICP-MS), and microbiological limits where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store at 15–25°C in a dry, well-ventilated area. Avoid exposure to moisture and elevated temperatures. Due to its light-sensitive (store away from light) nature, amber glass containers with inert gas headspace (N₂ or Ar) are recommended for long-term stability.
