Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 239.29 g/mol gives 2-(Benzylamino)-4-fluoro-4-methylpentanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-(Benzylamino)-4-fluoro-4-methylpentanoic acid (CAS 2166902-39-0), molecular formula C13H18FNO2 and molecular weight 239.29 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 2-(Benzylamino)-4-fluoro-4-methylpentanoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 239.29 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.
As a certified reference material (CRM), 2-(Benzylamino)-4-fluoro-4-methylpentanoic 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.
