In the demanding field of pharmaceutical research and development, the quality and purity of chemical intermediates are non-negotiable. NINGBO INNO PHARMCHEM CO.,LTD. highlights the critical importance of these aspects for 3-Piperazinobenzisothiazole Hydrochloride (CAS: 87691-88-1). This compound, with its molecular formula C11H14ClN3S and molecular weight of 255.77 g/mol, serves as a vital precursor in the synthesis of various active pharmaceutical ingredients (APIs).

The specified purity level for 3-Piperazinobenzisothiazole Hydrochloride, often requiring an assay of ≥99.0%, is essential to ensure the integrity of subsequent chemical reactions. Impurities, even in trace amounts, can lead to side reactions, reduced yields, and, most critically, compromised safety and efficacy of the final drug product. Therefore, sourcing this intermediate from reliable suppliers like NINGBO INNO PHARMCHEM CO.,LTD. who adhere to strict quality control measures is paramount for any serious research or manufacturing endeavor.

The typical appearance of 3-Piperazinobenzisothiazole Hydrochloride as a white to slight yellow crystalline powder further attests to its quality. This physical characteristic, combined with controlled levels of moisture (≤1.0%) and individual/total impurities (≤0.5%/≤1.0%), provides chemists with confidence in its suitability for sensitive pharmaceutical synthesis. The ability to purchase this compound with such high standards simplifies the process of developing new therapies.

Whether for early-stage research, process optimization, or large-scale manufacturing, the consistent quality of 3-Piperazinobenzisothiazole Hydrochloride is a key factor for success. NINGBO INNO PHARMCHEM CO.,LTD. is committed to meeting these high standards, enabling pharmaceutical companies to advance their drug discovery programs and bring much-needed medications to market.
