Chemical Structure

Amphisol A CAS 3539-43-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 322.42 g/mol gives Amphisol A distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Amphisol A (CAS 3539-43-3), a certified reference material (molecular formula C16H35O4P, MW 322.42 g/mol) for analytical method development and quality control.

Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, Amphisol A is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 322.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

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.
