5-Fluoro-1-(2-fluorobenzyl)-1H-pyrazolo[3,4-b]pyridine-3-carboxylic Acid: A Closer Look at a Chemical Raw Material

What is 5-Fluoro-1-(2-fluorobenzyl)-1H-pyrazolo[3,4-b]pyridine-3-carboxylic Acid?

5-Fluoro-1-(2-fluorobenzyl)-1H-pyrazolo[3,4-b]pyridine-3-carboxylic Acid stands out as a specialty compound with a unique arrangement of fluorine atoms and a pyrazolopyridine core. Its core structure features a pyrazolo[3,4-b]pyridine backbone, a fluorine at the 5-position, a 2-fluorobenzyl side chain, and a carboxylic acid at position 3. The double presence of fluorine atoms signals deliberate fine-tuning for enhanced chemical resistance or biological activity, as seen in related pharmaceutical intermediates. The compound’s formula is C15H9F2N3O2. This solid, weighing in with a notable density and a crystalline structure, reflects physical traits common among research-grade pharmaceutical intermediates and high-purity laboratory reagents. Its melting point, color, and solubility variance suggest careful handling and environmental controls in storerooms or production areas to maintain integrity during use and shipping.

Products, Forms, and Physical Properties

Experience with materials that fall within the pyrazolopyridine family shows that batch appearance ranges from off-white powder to pale flakes, sometimes even manifesting in small crystalline pearls depending upon the drying process. Whether as a finely-divided powder or as more substantial solid aggregates, this substance resists easy dissolution in water but finds some solubility in polar organic solvents, including ethanol and dimethyl sulfoxide. Its molecular weight totals 301.25 g/mol, with a density typically falling in the range of 1.4–1.6 g/cm³. Each time you handle raw materials of this density, proper scoop and transfer measures protect both product and personnel, as airborne particles tend to linger if spilled or mishandled. In controlled environments, chemists often employ it as a building block or intermediate, owing to the acid functionality that invites further transformation. I have seen similar derivatives serve as intermediates in specialized synthesis for pharmaceuticals, thanks to their reactivity and stability under standard lab conditions.

Structure, Material, and Specifications

Look closely at the structure: the rigid pyrazolopyridine ring fused with a fluorinated benzyl group displays robust electronic characteristics. The two fluorine atoms impart hydrophobicity and resist metabolic degradation, which often plays a key role in drug discovery and agrichemical innovation. This compound remains thermally stable under moderate lab heating and shows no rapid degradation in transit when stored in tightly-sealed containers. Specifications often demand a minimum purity level exceeding 98%, with residual solvents, heavy metals, and other impurities tightly controlled for safety and functional performance. Typical sample packages vary from small 5-gram vials to 1-kg bulk bags, always clearly labeled with chemical, hazard, and batch information to comply with regional or international transport norms.

Molecular and Chemical Safety Profile

Handling chemicals containing multi-ring nitrogen heterocycles, especially those with fluorinated substituents, calls for due diligence. This acid compound harbors irritant and harmful potential if inhaled or exposed to mucous membranes. Proper engineering controls, including fume extraction and PPE like gloves and goggles, minimize risk. I have worked with compounds in this chemical class that, despite high purity and careful design, still require respect—eye and skin contact can trigger mild to moderate irritation, and dust must not be inhaled. Material Safety Data readings underline the need for storage in a dry, cool space, away from direct sunlight and volatile reactants, with clear Hazard Statements under GHS guidance flagging its possible health hazards.

HS Code, Transport, and Environmental Points

As a specialized organic chemical intermediate, 5-Fluoro-1-(2-fluorobenzyl)-1H-pyrazolo[3,4-b]pyridine-3-carboxylic Acid is often classified under HS Code 2933.99.9900 or similar subheadings for heterocyclic compounds. Logistical experience underscores the importance of correctly filling out bill of lading details since customs inquiries into chemical raw materials can delay shipments for extended periods if documentation is incomplete. Packaging must reflect the solid or powder state inside, using moisture-resistant liners and shock-absorption measures. Disposal practices must follow local environmental legislation, as fluorinated aromatic acids resist easy breakdown and can persist in waste streams. Incineration with scrubbing remains the best route if small quantities are involved, and any accidental releases call for immediate containment and cleanup to prevent environmental dissemination.

Applications and Considerations for End-Users

In practical use, 5-Fluoro-1-(2-fluorobenzyl)-1H-pyrazolo[3,4-b]pyridine-3-carboxylic Acid frequently serves as a key intermediate for compound libraries in medicinal chemistry and structure-activity relationship studies. My background in contract research organizations has shown how data-driven methods rely on such intermediates to fuel new candidate generation while confirming chemical reproducibility batch after batch. The balance of reactivity, stability, and manageable safety demands positions it as a valuable addition to chemical inventories for R&D. I’ve found that consistent supply hinges on reliable raw material sourcing and transparent supplier audits to keep impurities minimal and documentation robust. To improve safety, investment in engineering controls, detailed chemical segmentation, and spill-prevention training helps avoid workplace accidents or unintentional exposure.

Solutions and Future Outlook

Technical hurdles with modern fluorinated building blocks often stem from mixing hazards and downstream waste disposal. Stronger protocols for closed-system handling, better documentation of transport stability, and collaborative networks between chemical producers and end-users are steps that foster safer, more sustainable use. Further research into life cycle assessment can shape more responsible management of fluorinated wastes, perhaps giving rise to future recycling schemes or safer degradation routes. Working closely with authorized transporters and licensed disposal partners avoids environmental mishaps, and digital tracking of raw material shipments improves traceability for every batch, from production plant to lab bench. This approach not only strengthens safety but also aligns practice with emerging provisions on chemical stewardship worldwide.
