Naproxen EP Impurity O is chemically 6-Methoxynaphthalene-2-carboxylic acid (as per EP). It is also known as Naproxen USP Related Compound A ; Naproxen Carboxylic Impurity ; 6-methoxy-2-naphthoic acid (EP). Naproxen EP Impurity O is supplied with detailed characterization data compliant with regulatory guideline. Naproxen EP Impurity O can be used for the analytical method development, method validation (AMV), Quality Controlled (QC) application for Abbreviated New Drug Application (ANDA) or during commercial production of Naproxen.

The product can be used as reference standards and further traceability against pharmacopeial standards (USP or EP) can be provided based on feasibility. SynZeal products are for analytical purpose only and not for human use.
