Parecoxib Sodium API Introduction
Parecoxib Sodium API is a highly selective non-steroidal precursor product of cyclooxygenase -2(COX-2) inhibitor. As a sodium salt with high water solubility, it is rapidly hydrolyzed by liver enzymes in vivo and converted into active metabolite Valdecoxib, thus exerting powerful analgesic, anti-inflammatory and antipyretic effects, and significantly reducing the common adverse effects of traditional non-selective inhibitors on gastrointestinal mucosa and platelet function. At the level of API, its synthesis process and quality control have high technical barriers, involving the construction of key chiral centers, stable crystal form control and strict impurity spectrum monitoring. The production of raw materials should meet the requirements of high purity and low impurities, especially the control of related substances, residual solvents and metal impurities is extremely strict to ensure safety and effectiveness.

FAQ
Q1:What is the stability data of the product? How long is the recommended storage condition and validity period?
A1: According to the long-term stability test and accelerated test data we have completed, the quality of the product is stable under the specified storage conditions. We recommend that it be stored in the original packaging at room temperature (15-25 C), which is dark and dry. At present, the long-term stability data has supported the validity of at least 36 months. We can provide a complete stability study protocol and report.
Q2:What is the MOQ and lead time?
A2: Our standard minimum order quantity is 1kg (depending on the purity specification). The regular delivery cycle is about 4-6 weeks after receiving the advance payment and confirming the order.
Q3:Do you provide custom packaging?
A3:We provide international standard pharmaceutical packaging (such as aluminum foil bags lined with double polyethylene bags and placed in sealed HDPE barrels), and can customize labels and packaging specifications according to customers' specific requirements to ensure the stability of products during transportation and storage.
