The Chemical Nature of cas 122 57 6
Hydrazine monohydrochloride, identified by the reference cas 122 57 6, is a critical organic salt characterized by its molecular formula H4N2.HCl. This compound exists as colorless flaky crystals, providing a manageable physical form for industrial handling compared to anhydrous hydrazine. Its molecular weight of 68.50 makes it a lightweight yet potent reagent for the introduction of hydrazine moieties into complex organic molecules.
The primary value of cas 122 57 6 lies in its ability to act as a stable source of hydrazine. By pairing the hydrazine base with hydrochloric acid, the resulting salt exhibits a melting point between 87-92℃, which allows for precise thermal control during reactions. This stability is crucial when synthesized for use as pharmaceutical intermediates, where inconsistent reagent behavior can lead to costly batch failures.
Industrial Significance of Hydrazine monohydrochloride
In the broader context of the chemical manufacturing industry, cas 122 57 6 serves as a cornerstone for the creation of various nitrogen-containing heterocycles. These structures are pervasive in the pharmaceutical industry, forming the backbone of numerous antihypertensive, antibacterial, and antiviral medications. The ability to provide a high-purity salt ensures that side reactions are minimized.
The global demand for high-assay intermediates has increased as ISO standards for pharmaceutical production become more stringent. Utilizing a product with an assay of ≥98.0% ensures that the stoichiometric calculations in large-scale reactors remain accurate. This precision reduces waste and enhances the overall "Green Chemistry" profile of the production facility by minimizing byproduct formation.
Furthermore, the role of cas 122 57 6 extends beyond simple synthesis. It acts as a reliable building block in the development of specialized ligands and catalysts. As the industry pivots toward more sustainable manufacturing processes, the stability and predictability of this specific intermediate become indispensable for R&D laboratories worldwide.
Technical Specifications and Quality Control
The technical integrity of cas 122 57 6 is defined by its rigorous purity parameters. A critical metric is the "Loss on drying," which must be maintained at ≤0.5% to prevent moisture-induced degradation of the reagent during the synthesis process. This low moisture content ensures that the reagent does not introduce unwanted water into anhydrous reactions.
Iron (Fe) contamination is another vital parameter for cas 122 57 6, kept strictly at ≤0.001%. In pharmaceutical synthesis, trace metals can act as unintended catalysts, leading to the formation of impurities or the degradation of the final API. Therefore, the ultra-low iron content is a hallmark of industrial-grade purity.
To maintain these specifications, the product is typically supplied in 25kg fiber drums, designed to protect the colorless flaky crystals from environmental contamination. Adhering to the assay of ≥98.0% ensures that cas 122 57 6 remains a consistent and dependable component in high-throughput chemical manufacturing.
Performance Metrics in Pharmaceutical Synthesis
When evaluating the efficacy of cas 122 57 6 in a lab setting, the focus shifts to its reactivity and solubility profiles. Because it is a salt, its solubility in polar solvents is enhanced, allowing for more homogeneous reaction mixtures. This is particularly advantageous in the synthesis of hydrazones and other nitrogenous derivatives.
The reliability of cas 122 57 6 can be measured by the purity of the resulting intermediates. When compared to other hydrazine sources, the monohydrochloride form often yields a cleaner reaction profile, reducing the need for extensive post-reaction purification steps like recrystallization or column chromatography.

Global Application and Market Integration
The application of cas 122 57 6 spans across several continents, with significant clusters in the pharmaceutical hubs of Asia and Europe. In these regions, the compound is utilized not only in the synthesis of new drugs but also in the production of diagnostic reagents. Its role as a pharmaceutical intermediate makes it a staple in the supply chains of generic drug manufacturers.
Integration of cas 122 57 6 into automated synthesis platforms is an emerging trend. Because it is a crystalline solid, it can be precisely dispensed by robotic weighing systems, allowing for the high-throughput screening of chemical libraries. This digitalization of the lab environment relies heavily on the consistent physical properties of the reagent.
Storage and Safety Protocols for Stability
Ensuring the longevity of cas 122 57 6 requires strict adherence to storage protocols. The compound must be stored in a cool, dry place, and it is imperative to isolate it from air. Since it is sensitive to oxidation and moisture, the use of airtight containers or inert gas blanketing is highly recommended for long-term storage.
From a safety perspective, handling cas 122 57 6 demands standard chemical hygiene practices. While the salt form is more stable than the liquid base, users should still utilize appropriate personal protective equipment (PPE) to avoid inhalation of crystals or skin contact. Proper ventilation in the workspace is a prerequisite for industrial use.
When managing inventory, the 25kg fiber drum packaging of cas 122 57 6 provides an excellent balance between bulk storage efficiency and ease of handling. By maintaining a "First-In, First-Out" (FIFO) system and monitoring storage temperatures, facilities can ensure that the assay remains ≥98.0% throughout the shelf life of the product.
Comparative Analysis of Intermediate Salts
When comparing cas 122 57 6 to other hydrazine salts, such as the sulfate or oxalate forms, the hydrochloride salt often stands out due to its specific solubility and reactivity. The chloride ion is generally less coordinating than sulfate, which can be a deciding factor in reactions where metal catalysts are present and coordination must be avoided.
The physical form of cas 122 57 6 as a colorless flaky crystal also offers logistical advantages. Flaky crystals tend to be less prone to caking than fine powders, facilitating easier pouring and measuring in industrial settings. This physical characteristic contributes to the overall efficiency of the manufacturing process.
Ultimately, the choice of cas 122 57 6 is a balance of cost, stability, and chemical compatibility. For the majority of pharmaceutical intermediate applications, the monohydrochloride provides the optimal profile for achieving high yields with minimal purification efforts.
