Amoxicillin Related Products
Amoxicillin is an antibiotic in the aminopenicillin subclass of the penicillin family. It is commonly prescribed to treat various bacterial infections, including middle ear infections, strep throat, pneumonia, skin infections, odontogenic infections, and urinary tract infections. amoxicillin works by blocking the production of bacterial cell walls, ultimately causing the bacteria to be destroyed.
Vsquare is a leading innovator in pharmaceutical reference standards. We supply high-quality Reference Standards of Amoxicillin, pharmacopeial and non-pharmacopeial Amoxicillin impurities, metabolites, stable isotope products, and nitrosamines (N-NO products). Amoxicillin impurities reference standards are useful in pharmaceutical research. They are useful in product development, ANDA and DMF filing, quality control (QC), method validation, and stability studies. It is also useful in the identification of unknown impurities and the assessment of genotoxic potential.
Amoxicillin-related products are thoroughly characterized. Amoxicillin products are supplied with detailed COA & analytical data meeting regulatory compliance. We can also provide EP/USP traceable standards based on your requirements. The supplied products are re-tested at regular intervals.
