Metformin Related Compounds & Impurities

Metformin is a biguanide that reduces hepatic glucose production and improves insulin sensitivity, the first-line oral agent for type 2 diabetes mellitus.

These materials support pharmaceutical research and development, product development, ANDA and DMF submissions, quality control (QC), analytical method development and validation, stability studies, impurity identification, and genotoxic impurity assessment.

Our Metformin-related reference standards are thoroughly characterized using advanced analytical techniques and are supplied with comprehensive Certificates of Analysis (COA) and supporting analytical data from our USFDA certified, ISO 17025 and ISO 17034 accredited Lab, to meet global regulatory expectations.
