Description

2-Pyrimidinesulfinic Acid (9Ci) is a specialized organic sulfur compound belonging to the pyrimidine class, serving as a valuable synthetic intermediate. Its sulfinic acid functional group makes it a versatile building block for constructing more complex molecules, particularly in the development of active pharmaceutical ingredients (APIs) and advanced materials. This high-purity intermediate is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and fine chemical sectors seeking to innovate within heterocyclic chemistry.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders, antiviral agents, and enzyme inhibitors.
• Agrochemical Synthesis: Used in the research and development of new herbicides, fungicides, and plant growth regulators that utilize the pyrimidine scaffold.
• Ligand and Catalyst Development: Employed in organometallic chemistry to create novel ligands for catalysis and metal-organic frameworks (MOFs).
• Material Science Research: Acts as a monomer or functionalization agent in the development of specialty polymers and organic electronic materials.
• Chemical Biology Probes: Utilized to synthesize probes for studying biological pathways and protein functions due to its modifiable sulfinic acid group.
• Custom Synthesis and Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for bespoke synthesis projects requiring high-purity heterocyclic intermediates.

Quality Control

Every batch of 2-Pyrimidinesulfinic Acid (9Ci) is manufactured under strict quality management systems and undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide full traceability and detailed Certificates of Analysis (COA) with each shipment, which include results from HPLC, NMR, and mass spectrometry. Our quality commitment aligns with cGMP principles for pharmaceutical intermediates, ensuring reliability for your critical R&D and production processes.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. Due to its sensitivity to oxidation, the container should be kept sealed under positive pressure of inert gas after each use to maintain product integrity.
