Hydroquinone, identified by its CAS No. 123-31-9, is a chemical compound whose utility is intrinsically linked to its purity and adherence to specific quality parameters. NINGBO INNO PHARMCHEM CO.,LTD. recognizes the importance of these specifications for our clients in the pharmaceutical and chemical industries, and we are committed to delivering products that consistently meet and exceed expectations.

At the forefront of Hydroquinone's specifications is its assay, typically required to be 99% or higher. This high level of purity is crucial for its role as a key ingredient in pharmaceutical formulations and as a reliable intermediate in various chemical synthesis pathways. NINGBO INNO PHARMCHEM CO.,LTD. ensures that our pharmaceutical chemical purity Hydroquinone meets this stringent requirement through rigorous quality control measures at every stage of production.

Another critical physical property is the melting point. For Hydroquinone, a sharp melting point within the 171-175 °C range is indicative of high purity. This parameter is carefully monitored by NINGBO INNO PHARMCHEM CO.,LTD. to guarantee the consistency and reliability of our product. Additionally, the visual appearance—described as white to grayish-white flakes—is a primary indicator that is easily verifiable upon receipt of the material.

Beyond these primary specifications, the control of impurities is vital. Parameters such as ignition residue, and the limits for heavy metals like Lead (Pb) and Iron (Fe), are critical for many applications, especially those in the pharmaceutical sector. NINGBO INNO PHARMCHEM CO.,LTD. adheres to strict limits for these impurities, ensuring that our Hydroquinone 99% purity product is safe and effective for its intended use. Buyers often search for terms like buy Hydroquinone 99% purity, underscoring the demand for such high standards.

In summary, the specifications for Hydroquinone (CAS 123-31-9) are designed to ensure its effectiveness and safety in various applications. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing Hydroquinone that meets these exacting chemical standards, making us a trusted source for businesses seeking high-quality chemical ingredients.
