Product Name:Clopidogrel Bisulfate
CAS:120202-66-6
MF:C16H16ClNO2S.H2O4S
Melting point :174-176°C
form:powder
color:White or almost white
Uses:
Prevention of Atherothrombotic Events: Indicated for patients with recent myocardial infarction (from a few days to less than 35 days), ischemic stroke (from 7 days to less than 6 months), or diagnosed peripheral arterial disease.
Acute Coronary Syndrome (ACS): Including non-ST-elevation ACS (such as unstable angina) and ST-elevation ACS. These patients typically require combination therapy with aspirin to further reduce the risk of cardiovascular events.
Excellent Physicochemical Properties and Solubility: The substance appears as a white to off-white crystalline powder with good solubility in water, methanol, ethanol, or glacial acetic acid. This favorable water solubility helps improve the oral bioavailability of the drug and facilitates subsequent formulation development.
High Chemical Stability: Under appropriate storage conditions, the API exhibits good thermal and photostability, which helps extend the product's shelf life and reduces quality risks during production and distribution.
Mature Synthesis and Scale-up Process: As a globally established classic cardiovascular drug, its API synthesis route is highly mature. This enables large-scale, cost-effective green manufacturing. Furthermore, impurity control standards are well-defined, fully meeting the strict quality requirements of major pharmacopoeias (such as ChP, USP, and EP).
