Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 186.14 g/mol gives (4-Methylbenzyl)phosphonic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (4-Methylbenzyl)phosphonic acid (CAS 13081-74-8), a certified reference material (molecular formula C8H11O3P, MW 186.14 g/mol) for analytical method development and quality control.
Owing to a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, (4-Methylbenzyl)phosphonic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 186.14 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 (4-Methylbenzyl)phosphonic acid 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.
