Chemical Structure

Tetrabutylphosphoniumhydrogensulfate CAS 108203-01-6 chemical structure

Description

As a certified reference material (CRM), Tetrabutylphosphoniumhydrogensulfate 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.

CATO supplies Tetrabutylphosphoniumhydrogensulfate (CAS 108203-01-6), a certified reference material (molecular formula C16H36PHO4S, MW 356.50 g/mol) for analytical method development and quality control.

Owing to a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, Tetrabutylphosphoniumhydrogensulfate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 356.50 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.

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