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 4-Fluorobenzothiohydrazide (CAS 518015-39-9), a certified reference material (molecular formula C7H7FN2S, MW 170.21 g/mol) for analytical method development and quality control.
Owing to a nitrile group, sulfur-containing functionality, fluorine substitution, an aromatic ring system, 4-Fluorobenzothiohydrazide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 170.21 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).
As a certified reference material (CRM), 4-Fluorobenzothiohydrazide 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.
