Chemical Structure
Description
(+/-)-2-Amino-4-Phosphonobutyric Acid (CAS 20263-07-4) is a high-purity analytical reference standard with the molecular formula C4H10NO5P and a molecular weight of 183.10 g/mol.
The molecular framework of (+/-)-2-Amino-4-Phosphonobutyric Acid (C4H10NO5P) is characterized by a carbohydrate-derived structure, an amide group, a phosphate ester group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), (+/-)-2-Amino-4-Phosphonobutyric 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.
