4-Hydrazinobenzoic acid (CAS 619-67-0) stands as a pivotal chemical compound, widely recognized for its integral role in advanced pharmaceutical synthesis. This high-purity intermediate is essential in the production of critical medications, demonstrating its significance across various chemical and pharmaceutical industries. NINGBO INNO PHARMCHEM CO.,LTD. is a dedicated manufacturer and supplier committed to providing this vital compound with exceptional quality and reliability.
Known by its chemical name, 4-Hydrazinobenzoic acid, and identified by its CAS number 619-67-0, this compound presents as a yellow-brown crystalline powder. Its molecular formula is C7H8N2O2, with a molecular weight of approximately 152.15 g/mol. These precise chemical characteristics ensure its suitability for demanding applications where consistency and purity are paramount.
The physical and chemical properties of 4-Hydrazinobenzoic acid are well-defined, contributing to its versatility and stability in industrial processes. It possesses a density of 1.4±0.1 g/cm3 and a melting point of 218 °C (decomposes). The boiling point is typically around 274.61°C (estimated), although some data suggests a higher boiling point of 377.2±25.0 °C at 760 mmHg. Its flash point is recorded at 181.9±23.2 °C, and its vapor pressure is negligible at 0.0±0.9 mmHg at 25°C. The index of refraction is approximately 1.694. This compound is noted for its stability, though it is combustible and incompatible with strong acids and strong oxidizing agents, requiring careful handling and storage.
In terms of quality, 4-Hydrazinobenzoic acid from NINGBO INNO PHARMCHEM CO.,LTD. adheres to stringent specifications. It boasts an assay (HPLC) of ≥99.0%, ensuring its high purity for sensitive applications. The melting point is consistently at or above 200°C, and the ash content is maintained at ≤3.0%, reflecting the meticulous quality control during its production.
The primary application of 4-Hydrazinobenzoic acid is its critical use as an intermediate in the synthesis of Deferasirox (CAS: 201530-41-8). Deferasirox is an orally active tridentate iron chelator, a vital drug prescribed for the treatment of chronic iron overload. This condition often results from frequent blood transfusions in patients suffering from disorders such as thalassemia and sickle cell anemia. The purity and reliability of 4-Hydrazinobenzoic acid are therefore essential for the efficacy and safety of the final pharmaceutical product. Beyond Deferasirox, this compound also finds application in the synthesis of multi-substituted dihydropyrano[2,3-c]pyrazole derivatives and serves as a versatile organic building block for various other chemical and pharmaceutical compounds.
For packaging, 4-Hydrazinobenzoic acid is typically supplied in 25 kg drums, with the flexibility to accommodate diverse customer requirements for packaging size and type. Proper storage is crucial to maintain its integrity; it should be stored in a cool, well-ventilated place, away from direct sunlight, moisture, and incompatible substances. It is also recommended to keep it in a dark, inert atmosphere, especially for long-term storage under controlled temperatures (e.g., below -20°C).
