Chemical Structure
Description
The occurrence of Ethyl hydrogen benzylphosphonate is closely related to a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Ethyl hydrogen benzylphosphonate (CAS 18933-98-7), a certified reference material (molecular formula C9H13O3P, MW 200.17 g/mol) for analytical method development and quality control.
Owing to a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, Ethyl hydrogen benzylphosphonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 200.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Ethyl hydrogen benzylphosphonate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
