(S)-tert-butyl-(4-fluoro-3,5-dimethylphenyl)-4-methyl-3-(2-oxo-2,3-dihydro-1H-imidazol-1-yl)-6,7-dihydro-2H-pyrazolo[4,3-c]pyridine-5(4H)-Chemicalbookcarboxylate;(S)-1-[5-Boc-2-(4-fluoro-3,5-dimethylp

Its key physicochemical properties are as follows: it is soluble in polar organic solvents such as dichloromethane, methanol, and ethanol, slightly soluble in water, and insoluble in non-polar solvents like petroleum ether. This characteristic facilitates column chromatography or recrystallization purification in organic synthesis. The melting point is usually 155–160℃, and the purity of reagent-grade products is generally ≥98% (determined by HPLC), which can meet the requirements of pharmaceutical R&D and fine chemical synthesis. The tert-butoxycarbonyl group (Boc, -COOC(CH₃)₃) in the molecular structure ensures stability during intermediate reactions and can be deprotected under acidic conditions when needed.

As an important chiral pharmaceutical intermediate, this compound is mainly used in targeted drug R&D, especially in the synthesis of pyrazolo[4,3-c]pyridine derivatives with potential anti-tumor, anti-inflammatory, or kinase inhibitory activities. Its molecular structure integrates multiple active fragments: the 4-fluoro-3,5-dimethylphenyl group can optimize the lipophilicity and metabolic stability of target products, the imidazolinone structure can enhance the binding affinity to biological targets, and the chiral configuration ensures its specific interaction with biomacromolecules. It can also serve as a key building block for fine chemical synthesis and heterocyclic compound modification.

In terms of safety and storage, this compound is slightly irritating to the skin and respiratory tract. Protective gloves and goggles should be worn during operation, and the contacted area should be rinsed immediately with plenty of water after contact. It is incompatible with strong oxidants and strong acids (to avoid cleavage of the tert-butoxycarbonyl group). It should be sealed in a light-proof container and stored in a cool (2–8℃), dry, and well-ventilated place, away from moisture and high temperatures to prevent structural degradation or racemization.
