It is an impurity of the widely used antidiabetic drug, metformin, that belongs to the biguanide class of compounds.
Application
This pharmaceutical secondary standard can also be used as follows:
- Separation and estimation of metformin along with other antidiabetics from meglitinides class in the presence of metformin impurity cyanoguanidine using a liquid chromatography method in pharmaceutical formulations
- Development of a reversed phase-high performance liquid chromatographic (RP-HPLC) method combined with a UV-diode array detector (PDA) for the impurity analysis of combined dosage tablet of metformin hydrochloride and teneligliptin hydrobromide hydrate
- Estimation of empagliflozin, linagliptin, along with metformin and its related impurities cyanoguanidine and melamine using HPLC-DAD and high-performance thin layer chromatography (HPTLC) methods in their combined tablets
- Development and validation of a stability indicating capillary zone electrophoresis (CZE) method for the quantification of metformin and its major impurity in pharmaceutical formulation
- Simultaneous determination of vildagliptin, metformin, and metformin-related compounds (A, B, and C) in tablets using a high-performance liquid chromatography-tandem mass spectrometry method (HPLC-MS/MS)
Analysis Note
These secondary standards offer multi-traceability to the USP, EP (PhEur) and BP primary standards, where they are available.

Self-assembly of a trigonal building subunit with diaminotriazines (DAT) functional groups leads to a unique rod-packing 3D microporous hydrogen-bonded organic framework (HOF-3). This material shows permanent porosity and demonstrates highly selective separation of C2H2/CO2 at ambient temperature and pressure.
