Product Description
Products Description of Orthoboric Acid CAS#10043-35-3
Orthoboric acid, commonly known as boric acid (H₃BO₃), is an inorganic crystalline compound formed by dissolving boron trioxide in water. Among boric acids, it has the highest water content and the greatest stability. It appears as white, shiny powdery or flaky crystals, is odorless, slightly bitter, and feels smooth to the touch. Boric acid is soluble in water, ethanol,glycerin, ethers, and essential oils, and its aqueous solution is weakly acidic with typical Lewis acid behavior.
When heated, orthoboric acid gradually dehydrates: forming metaboric acid at 70–100 °C, pyroboric acid at 150–160 °C, and boron oxide (B₂O₃) at about 300 °C. Its solubility in water increases markedly with temperature. The presence of hydrochloric, citric, or tartaric acid enhances its solubility, allowing purification by recrystallization.
Product Application of Orthoboric Acid CAS#10043-35-3
Orthoboric acid is widely used in molecular biology research, including DNA and RNA purification, preparation of biological buffers, and as a reagent in biochemical experiments. It is also applied in plant science to evaluate the effects of boron toxicity on crop growth and antioxidant systems, such as in maize root studies. In biomedical research, boric acid is used to investigate boron absorption and distribution in animal tissues, including studies on uptake in different regions of the brain after injection.

FAQ
Q1: Is Huafeng Chemical a manufacturer or a trader?
A: We are a professional service provider specializing in chemical foreign trade. Rather than being limited to the products of a single factory, we leverage the chemical industry cluster in Shandong Province to integrate production resources from multiple high-quality manufacturers. This allows us to offer a wide range of sourcing options—covering various product categories and origins—instead of simply pushing a single product. Furthermore, our core competitiveness lies in our professional foreign trade services (covering documentation, logistics, and regulatory compliance), ensuring a smooth and worry-free procurement process for you.
Q2: How is the security of my transaction guaranteed when working with Huafeng Chemical?
A: We strictly adhere to international trade rules (Incoterms® 2020) and accept various payment methods, such as Letters of Credit (L/C) and Telegraphic Transfers (T/T). For new clients, we support small-batch trial orders and can clearly define arbitration clauses and applicable laws within the contract. Additionally, we maintain a robust risk management system to help you mitigate common trade risks, such as exchange rate fluctuations, shipping delays, and document discrepancies.
Q3: Do you have experience serving clients in Russian-speaking regions?
A: Yes. We place great importance on the Russian-speaking market; our team includes Russian-speaking business professionals who are well-versed in the import regulations of Russia and the Eurasian Economic Union (EAEU). We understand the importance of EAC certification to clients in these regions and can assist with related compliance inquiries. We have established connections with chemical traders across various CIS countries and have gained valuable experience in specialized packaging and temperature-controlled shipping designed to withstand harsh local winter conditions.
Q4: How do you guarantee product quality?
A: We implement a strict supplier qualification and periodic audit system. A Certificate of Analysis (COA)—issued by the original manufacturer—is provided with every shipment. We also welcome pre-shipment inspections conducted by internationally recognized third-party agencies such as SGS, BV, or ITS. Should the test results fail to meet the standards specified in the contract, you have the right to reject the goods or request a replacement.
