Chemical Structure

Bis(2-ethylhexyl) phosphite CAS 3658-48-8 chemical structure

Description

Based on its molecular formula C16H35O3P, Bis(2-ethylhexyl) phosphite contains a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 306.42 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Bis(2-ethylhexyl) phosphite (CAS 3658-48-8) is a high-purity analytical reference standard with the molecular formula C16H35O3P and a molecular weight of 306.42 g/mol.

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), Bis(2-ethylhexyl) phosphite 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.
