Chemical Structure
Description
Phosphonoformic acid (CAS 4428-95-9) is a high-purity analytical reference standard with the molecular formula CH3O5P and a molecular weight of 126.01 g/mol.
Owing to a phosphate ester group, Phosphonoformic acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 126.01 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Phosphonoformic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
