Allopurinol EP Impurity E (CAS 31055-19-3) is a specialized chemical entity used extensively in the pharmaceutical industry as a reference standard. It is chemically identified as Ethyl 3-formamido-1H-pyrazole-4-carboxylate and serves as a critical marker for monitoring the synthesis and degradation pathways of Allopurinol, a common medication for gout and hyperuricemia.
In the Indian pharmaceutical landscape, this impurity is highly sought after by R&D laboratories and Quality Control departments of API manufacturing units. As India continues to strengthen its position as a global hub for generic drug manufacturing, the demand for high-purity reference standards that comply with European Pharmacopoeia (EP) and USP guidelines has grown significantly to meet stringent regulatory export requirements.
Procurement of this chemical requires careful attention to documentation, specifically the Certificate of Analysis (CoA) and Material Safety Data Sheet (MSDS). Buyers should source from reputable suppliers who provide traceable analytical data, as the material is typically utilized in highly sensitive analytical procedures where purity and stability are paramount for regulatory compliance.
