Explore our foundational chemical compounds engineered to rigorous international purity benchmarks.
Chromic Nitrate, specifically Chromium(III) Nitrate Nonahydrate [Cr(NO₃)₃·9H₂O] (CAS No: 7789-02-8), stands as a vital precursor compound within global chemical processing operations. It exists in the form of dark violet crystals, characterized by its high solubility in water and alcohol. Its critical chemical properties make it irreplaceable in catalytic synthesis, glass finishing processes, and advanced surface metal treatments.
As an industry-leading partner in mainland China, Yanxatech System Industries Limited collaborates directly with primary chemical refineries to offer bespoke grades. From standard industrial formulations targeting corrosion inhibition to ultra-high-purity batches targeting precision petrochemical catalysts, our material matches strict requirements for minimum organic compounds and zero chloride trace elements.
Understanding its synthesis pathway—involving the reaction of chromium hydroxide or chromic acid with nitric acid under thermal monitoring—enables our quality assurance team to regulate the crystal geometry, preventing premature degradation during international storage and bulk shipping transits.

A premier Chinese manufacturing and sourcing gateway for high-performance specialty materials since 2008.
Established in 2008 as a focused specialty business unit, YANXA has evolved into a global supplier. We leverage strong ties to Chinese heavy chemical institutes to export premium specialty chemical and mechanical manufacturing aids. Our operational roadmap links scientific material properties with the demands of top-tier industrial conglomerates worldwide.
Cooperating with leading manufacturers and the renowned research institutes in the field of specialty chemicals in China, YANXA is capable of supplying:
Quality, safety and efficiency prevail over all other values in our business. We address general customer needs as well as specific, customized requirements for newly developed applications. Adhering strictly to technical guidelines, YANXA delivers chemicals safely to ensure protection of human health and the global environment.
How we integrate green production and smart supply chains to deliver a stable global supply of Chromium(III) Nitrate.
In recent years, the manufacturing landscape in China has undergone a major transition, shifting from low-cost output to environmentally responsible production. Our factories feature Zero Liquid Discharge (ZLD) systems that recycle water and process waste, ensuring compliance with strict domestic environmental standards.
Through automatic DCS (Distributed Control Systems) monitoring, we maintain tight control over chemical reactions. This keeps trace impurities like Chloride, Sulfate, and Iron consistently low, ensuring high quality in every batch of Chromic Nitrate.
This supply chain resilience allows us to support long-term production contracts, mitigating the risk of supply disruptions for global buyers in the electronics, catalysts, and aerospace sectors.
Innovating new material pathways and aligning with clean global chemistry policies.
Regulatory frameworks like REACH restrict Hexavalent Chromium (Cr VI) due to its high toxicity. Chromic Nitrate acts as a key precursor for Trivalent Chromium (Cr III) compounds, providing a safer alternative for electroplating and corrosion passivation.
Research shows that trace doping with high-purity chromium oxides derived from Chromic Nitrate precursors improves the structural stability and electrochemical performance of lithium-rich cathode materials.
Our catalyst-grade Chromic Nitrate features low levels of alkali metals (sodium, potassium). This ensures clean calcination profiles, allowing manufacturers to create highly active, long-lasting catalysts for dehydrogenation reactions.
Purchasing industrial-scale Chromic Nitrate requires a clear understanding of international chemical trade guidelines. Classed as an oxidizer, Chromic Nitrate falls under UN Number 2720, Class 5.1 hazardous goods regulations.
Yanxatech provides custom compliance packages to assist global sourcing agents. We secure proper hazard containment packaging, compile comprehensive safety documentation (such as GHS-compliant SDS), and coordinate export clearances at Chinese deep-water ports (including Shanghai and Qingdao).
Whether you require standard 25kg multi-layer anti-static bags, reinforced fiber drums, or custom bulk quantities, our team ensures your materials arrive safely, intact, and fully compliant with local regulatory policies.
Technical profiles for our high-volume organic intermediates.
A colorless liquid that polymerizes easily and is highly soluble in water, alcohol, and ether. Rapidly oxidizes to formic acid in air, acting as a strong reducing agent. Typically supplied as formalin, a 37-50% solution stabilized with methanol to prevent polymerization.
Also known as HMTA (CAS No: 100-97-0), this white crystalline powder is produced via the condensation of formaldehyde and ammonia. It serves as a versatile intermediate in thermosetting resins, rubber vulcanization, and explosives manufacturing.
A high-quality, solid alternative to liquid formalin. Features a low water content (≤ 0.05% formic acid) and a rapid dissolution rate (≤ 40 minutes). Suitable for agricultural chemicals, synthetic resins, and paint formulations.
