Chemical Structure

Metformin EP Impurity B Dinitrate CAS 27369-26-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Metformin EP Impurity B Dinitrate.

CATO supplies Metformin EP Impurity B Dinitrate (CAS 27369-26-2), a pharmacopoeial impurity reference standard (molecular formula C4H8N8HNO3, MW 231.18 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Metformin EP Impurity B Dinitrate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 231.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

CATO manufactures Metformin EP Impurity B Dinitrate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
