In the intricate world of pharmaceutical manufacturing, understanding and controlling impurities is as critical as synthesizing the active pharmaceutical ingredient (API) itself. Darunavir Impurity A, with its distinct CAS number 169280-56-2, is a prime example of a compound that holds significant importance in the quality assurance of Darunavir, a widely used antiviral drug. NINGBO INNO PHARMCHEM CO.,LTD. provides this essential material, emphasizing its role in maintaining rigorous pharmaceutical standards.

The chemical identity of Darunabin Impurity A is crucial. Its molecular formula, C20H29N3O3S, and molecular weight of 391.53, combined with its appearance as a white crystal powder and an assay of ≥98% MIN, define its quality and suitability for use. For professionals looking to buy Darunabin intermediate, these specifications are key indicators of purity and reliability. Adherence to pharmacopeial standards such as USP, BP, EP, and FCC further solidifies its position as a trustworthy component in drug synthesis and analysis.

The primary application of Darunabin Impurity A is as a vital Darunabin synthesis intermediate. Its presence and purity directly influence the outcome of the manufacturing process, impacting the final API’s efficacy and safety profile. Beyond its role in synthesis, it also serves as a critical pharmaceutical impurity reference standard. This allows quality control laboratories to accurately identify and quantify any trace amounts of this compound that might be present in the final drug product, ensuring compliance with regulatory limits.

For any pharmaceutical company aiming to produce high-quality Darunavir, partnering with a reliable 4-AMINO-N-[(2R,3S)-3-AMINO-2-HYDROXY-4-PHENYLBUTYL]-N-ISOBUTYLBENZENE-1-SULFONAMIDE supplier like NINGBO INNO PHARMCHEM CO.,LTD. is a strategic imperative. The company's commitment to providing this intermediate with guaranteed purity and compliance supports pharmaceutical R&D, formulation development, and the crucial batch release testing phases. Competitive pricing and readily available support further facilitate its adoption in the industry.

In summary, Darunavir Impurity A is more than just a byproduct or an intermediate; it is an integral part of the pharmaceutical quality ecosystem. Its precise characterization and reliable supply are fundamental for ensuring the safety and effectiveness of antiviral medications, making it a key player in pharmaceutical quality assurance.
