Product Details

Aminoguanidine Sulfate (also known as Aminoguanidine Hemisulfate; Hydrazinecarboximidamide sulfate (2:1)) is an organic guanidine derivative with the molecular formula C2H14N8SO4 (linear formula (CH6N4)2·H2SO4) and a molecular weight of 246.25. It is a white crystalline powder that is readily soluble in water and insoluble in ethanol. As a highly active hydrazine derivative, aminoguanidine is a well-established inhibitor of advanced glycation end-product (AGE) formation and serves as a key building block in the synthesis of pharmaceutical intermediates, heterocyclic compounds and other fine chemicals. In industrial classification, it belongs to guanidine derivatives under fine chemicals, with high purity requirements and broad applicability in pharmaceutical R&D, organic synthesis and related high-end fields.

Core Advantages

Readily soluble in water, forming a clear aqueous solution of weak acidity; insoluble in ethanol.

Thermally stable under routine storage conditions; decomposes only at approximately 206°C, supporting safe handling and storage.

Strong nucleophilic reactivity as a hydrazine derivative, making it an effective amination reagent in organic synthesis.

Low toxicity and no significant pungent odor, providing a high level of safety in storage, transportation and operation.

Excellent water solubility profile supports convenient dosing in aqueous reaction systems.

Stable powder form with consistent particle characteristics, easy to weigh, blend and dispense.

Key Application Fields

Pharmaceutical intermediates: key intermediate for the synthesis of drug intermediates and active pharmaceutical ingredients, including anti-inflammatory and antihyperglycemic compounds.

AGE-inhibitor research: as aminoguanidine is a well-documented inhibitor of advanced glycation end-product (AGE) formation, the sulfate salt is widely used in the R&D of therapeutic agents for diabetic complications and age-related disorders.

Organic synthesis & heterocyclic chemistry: a versatile nucleophilic building block for constructing triazoles, triazines, pyrazoles and other nitrogen-containing heterocycles.

Fine chemical research: a dependable high-purity reagent for laboratory and pilot-scale chemical development.

FAQ ：

Q1. What is the difference between Aminoguanidine Sulfate, Aminoguanidine Hydrochloride and Aminoguanidine Bicarbonate?

The three products share the same aminoguanidine cation and differ only in the counter-ion (sulfate, hydrochloride or bicarbonate), which affects water solubility, aqueous pH and handling characteristics. The sulfate salt is typically chosen when a sulfate counter-ion is preferred in downstream synthesis or formulation.

Q2. Is Aminoguanidine Sulfate soluble in water?

Yes, it is readily soluble in water, and its aqueous solution is weakly acidic. It is insoluble in ethanol.

Q3. At what temperature does it decompose?

It decomposes at approximately 206°C. Avoid heating the material above this temperature during processing.

Q4. How should Aminoguanidine Sulfate be stored?

Keep the container tightly sealed in a cool, dry and well-ventilated warehouse; protect from moisture, direct sunlight and contact with strong acids or oxidizing agents. Shelf life is 24 months under normal temperature and sealed conditions.

Q5. Can it be used directly in food or cosmetics?

No. It is a fine chemical intermediate intended for downstream synthesis, not a direct-use additive in finished consumer products.

Q6. What are the MOQ and packing?

The minimum order quantity is 500 kg. Standard packing is 25 kg fiber drums or 500 kg jumbo bags on pallets; customized packing is available on request.

Q7. What is the lead time?

The conventional lead time is 2–3 weeks, subject to order quantity and final confirmation.
