Phenyl Hydrazine Hydrochloride is a highly versatile aromatic hydrazine salt widely utilized in the Fischer Indole Synthesis. It serves as a crucial starting material in the synthesis of the entire carbazole pathway for Ondansetron and Carvedilol drug synthesis. Sourcing the hydrochloride salt from Kalpasthana ensures superior chemical stability, reduced volatility, and strict quality controlled manufacturing compared to the free base. We handle worldwide shipping with certified hazardous materials transport compliance.
Manufacturing Importance: Sourced directly from our state-of-the-art facility in Bidar District, Karnataka. Every batch is manufactured under strict quality controlled guidelines, ensuring predictable synthesis yields and batch-to-batch consistency.

Phenyl Hydrazine Hydrochloride is a highly versatile aromatic hydrazine derivative. It is a legendary reagent for the Fischer Indole Synthesis, making it the primary starting material for the entire carbazole pathway of Carvedilol and Ondansetron. It is also widely used in synthesizing pyrazolone-based anti-inflammatory drugs, organic pigments, dyestuffs, agricultural fungicides, and as an analytical reagent for identifying sugars and carbonyl compounds.
This hydrochloride salt is preferred in industrial pharmaceutical manufacturing over the free base due to its superior stability and reduced volatility. Its high purity is critical for preventing hydrazone-related impurities, which are highly regulated as potentially genotoxic substances in pharmaceutical intermediates.
Reacts with 1,3-cyclohexanedione to construct the tetrahydrocarbazolone ring for both APIs.
A core reagent for synthesizing pyrazoles, indoles, and pyrazolones in pharmaceutical and agrochemical sectors.
Classic reagent for converting reducing sugars into crystalline osazones and identifying aldehydes/ketones.
For Phenyl Hydrazine Hydrochloride, quality is our foundational pillar. We ensure high-purity hydrazine salt footprints through strict process controls, specialized hydrochloride salt crystallization, and EHS-compliant closed-loop synthesis. Our facility monitors reactions to minimize sulfate residues and free hydrazine impurities, guaranteeing batch-to-batch consistency for Fischer Indole and agrochemical syntheses.

Phenyl Hydrazine Hydrochloride is a hydrazine derivative. It is synthesized by the diazotization of aniline with sodium nitrite in hydrochloric acid, followed by reduction of the resulting diazonium salt using sodium sulfite or stannous chloride. The hydrochloride salt is precipitated as a stable, white to off-white crystalline powder.
Phenyl Hydrazine HCl is a vital intermediate in the synthesis of heterocyclic compounds. Its primary pharmaceutical application is reacting with 1,3-cyclohexanedione to produce 1,2,3,9-tetrahydrocarbazolone, which is converted to Ondansetron. It is also used in the synthesis of pyrazole derivatives, agrochemicals, and industrial dyes.
We supply premium Phenyl Hydrazine Hydrochloride with a validated purity of ≥99.0% (by titration/HPLC), strict controls on moisture content (≤1.0%), and a melting range of 243°C - 246°C (with decomposition) for robust synthesis yields.
It is packed in standard 25 kg fiber drums with double PE inner bag liners. Store in a dry, cool, well-ventilated warehouse under tight seals, isolated from strong oxidizers, light, and direct heat sources.
As a toxic and potential allergen compound, we handle it under strict EHS protocols. Sourcing teams receive COA, MSDS, and safety data sheets detailing required PPE, ventilation, and dust containment measures.
HPLC purity verified at >=99.0% with minimal related substances.
Continuous commercial-scale volume manufacturing capacity.
Complete analytical profiles, GC profiles, MSDS, and COA dossiers.
Equipped with a 50 kL combined reactor volume in Karnataka.

Commercial Sourcing & Synonyms: Sourcing high-purity Phenyl Hydrazine Hydrochloride under CAS No. 59-88-1 ensures batch-to-batch consistency. Operating as an established hydrazine derivatives manufacturer and Bulk Drug Intermediates supplier India partner, Kalpasthana supplies this key Carvedilol intermediate worldwide.
Phenyl Hydrazine Hydrochloride (Phenylhydrazine HCl) is a vital heterocyclic building block. In the pharmaceutical sector, it is a key reagent in the Fischer Indole Synthesis, which is the primary route to create carbazole and indole derivatives, including APIs like Carvedilol. It is also widely used to synthesize agrochemicals, dyes, and organic research compounds.
Our Phenyl Hydrazine Hydrochloride is a high-grade crystalline material with ≥99.0% purity. We stabilize the salt form to prevent the rapid oxidation that typically occurs with free hydrazine bases. We perform rigorous batch testing to ensure moisture, heavy metals, and free hydrazine levels are strictly minimized.
As a toxic and light-sensitive compound, Phenyl Hydrazine Hydrochloride requires careful handling in accordance with international safety regulations. It must be stored in airtight, corrosion-resistant 25 kg drums in a cool, dry area. We provide complete safety guidance, emergency protocols, and fully compliant global logistics.
