Chemical Structure

Perfluorododecanesulfonic acid CAS 79780-39-5 chemical structure

Description

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

CATO supplies Perfluorododecanesulfonic acid (CAS 79780-39-5), a certified reference material (molecular formula C12HF25O3S, MW 700.16 g/mol) for analytical method development and quality control.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, Perfluorododecanesulfonic acid is typically white to off-white amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 700.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO manufactures Perfluorododecanesulfonic 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.
