Hydrazine Compounds & Hydrazone Intermediates
Welcome to OUHE Technology’s catalog of hydrazine compounds and hydrazone intermediates. We supply high-purity alkylhydrazines, arylphenylhydrazines, and hydrazine salts essential for heterocyclic cyclization, active pharmaceutical ingredients (APIs), and specialty dye synthesis. Use our advanced search bar to filter by CAS number or product name to secure reliable intermediates.
High Nucleophilicity and Reversible Hydrazone Formation
The nitrogen-nitrogen single bond in hydrazines exhibits the classic alpha-effect, imparting exceptionally high nucleophilicity. At OUHE Technology, we provide hydrazines optimized for rapid condensation with aldehydes and ketones to form stable hydrazone intermediates. These intermediates serve as vital starting points for subsequent synthetic modifications, including Wolff-Kishner reductions and targeted molecular tagging.
Essential Scaffolds for Pyrazole and Indole Cyclization
-
Phenylhydrazines & Salts: Ideal precursors for the Fischer indole synthesis, yielding high-purity substituted indoles widely used in pharmaceutical discovery.
-
Alkylhydrazines & Hydrazides: Key bifunctional reagents utilized in the Knorr pyrazole synthesis and the preparation of triazoles and pyridazines.
-
Hydrazine Hydrochloride/Sulfate: Stabilized salt formulations designed to minimize oxidation and volatility while ensuring highly consistent reactant stoichiometric control.
Air-Oxidation Prevention, Toxicity Safety, and Quality Control
Many free-base hydrazines are toxic, volatile, and highly prone to air-oxidation. To preserve chemical integrity and prevent degradation, we package our reactive hydrazine compounds in hermetically sealed, nitrogen-blanketed containers under strict climate controls. Every batch undergoes rigorous GC or HPLC purity testing, supported by NMR verification in cooperation with top scientific institutions, and is shipped with complete GHS-compliant MSDS.
Frequently Asked Questions
A: Hydrazines are highly sensitive to atmospheric oxygen. We package our air-sensitive hydrazines in nitrogen-blanketed, hermetically sealed amber bottles or steel drums. We recommend storing these compounds under an inert atmosphere below 4°C.
A: Hydrazine salts (such as hydrochlorides or sulfates) are significantly more stable, less volatile, and less prone to air-oxidation than free bases. They ensure safer laboratory handling and precise stoichiometric measurements during synthesis.
A: We verify purity using high-resolution GC or HPLC analysis with specialized columns to prevent on-column decomposition. We also provide complete NMR and MS spectra through our university partnerships for absolute structural confirmation.
