In the pharmaceutical industry, the diligent management of impurities is a cornerstone of drug safety and regulatory compliance. For Hydrochlorothiazide, a widely used diuretic, understanding and controlling its impurities is paramount. Central to this effort is the availability of high-quality reference standards, such as Hydrochlorothiazide EP Impurity C, identified by CAS number 402824-96-8. This article serves as a guide for laboratories seeking to procure this essential compound.

Hydrochlorothiazide EP Impurity C, also known as the Hydrochlorothiazide dimer, is a substance that requires precise quantification in pharmaceutical manufacturing. As a pharmaceutical impurity reference standard, its primary function is to serve as a benchmark for analytical testing. Laboratories use it to validate chromatographic methods, establish impurity profiles, and ensure that their Hydrochlorothiazide batches meet strict quality specifications. The ability to reliably buy Hydrochlorothiazide EP Impurity C is therefore critical for maintaining robust Hydrochlorothiazide quality control procedures.

When selecting a supplier for CAS 402824-96-8, several factors are crucial. Firstly, the purity of the standard must be guaranteed, typically reported as ≥95%. Secondly, comprehensive documentation, including a Certificate of Analysis (CoA) detailing its chemical properties, molecular formula (C15H16Cl2N6O8S4), molecular weight (607.49 g/mol), and appearance (white to off-white solid), is essential. Understanding the chemical synthesis of Hydrochlorothiazide impurity C and the supplier's manufacturing processes can also provide confidence in the product's quality. Reputable suppliers like Ningbo Inno Pharmchem Co., Ltd. ensure that their products meet these stringent requirements, facilitating accurate drug analysis.

The applications of this impurity standard are broad, ranging from method development in analytical laboratories to routine quality testing in manufacturing facilities. It plays a vital role in ensuring that Hydrochlorothiazide meets pharmacopoeial standards and regulatory requirements. By having a reliable source for this compound, pharmaceutical companies can effectively manage the risks associated with impurities, thereby enhancing the safety and efficacy of their products. The availability of CAS 402824-96-8 in suitable pack sizes and with reliable shipping is also a key consideration for busy laboratories.

In conclusion, procuring Hydrochlorothiazide EP Impurity C (CAS 402824-96-8) is a strategic decision for any laboratory involved in Hydrochlorothiazide analysis. It represents a commitment to quality, safety, and regulatory compliance. By partnering with trusted suppliers who provide high-purity standards with thorough documentation, laboratories can ensure the integrity of their analytical results and contribute to the production of safe and effective pharmaceuticals.
