Description

Doxycycline EP Impurity B (HCl salt) also known in pharmacopoeias as Methacycline Hydrochloride is a thoroughly characterized reference standard. It meets strict regulatory standards including those set by USP EMA JP and BP. This product is crucial for use in Abbreviated New Drug Applications (ANDA) New Drug Applications (NDA) and the commercial production of Doxycycline. Additionally it comes with a detailed Structure Elucidation Report (SER) ensuring its precision and dependability for a variety of analytical uses. It is from second generation Tetracycline class of antibiotics. It is a synthetic derivative of oxytetracycline. Its absorption decreases with the antacids.
