Chemical Structure

Butylphosphonic Acid CAS 3321-64-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 138.10 g/mol gives Butylphosphonic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Butylphosphonic Acid (CAS 3321-64-0), molecular formula C4H11O3P and molecular weight 138.10 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Butylphosphonic Acid (C4H11O3P) is characterized by a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
