Metformin CAS 657-24-9 chemical structure

Description

CATO manufactures Metformin 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.

Metformin (CAS 657-24-9), molecular formula C4H11N5 and molecular weight 129.16 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, Metformin is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 129.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
