Chemical Structure

PRX-08066 Maleic acid CAS 866206-55-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 401.89 g/mol gives PRX-08066 Maleic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies PRX-08066 Maleic acid (CAS 866206-55-5), a certified reference material (molecular formula C19H17ClFN5S, MW 401.89 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution, PRX-08066 Maleic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 401.89 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), PRX-08066 Maleic acid 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.
