3,4-Diphenylselenophene-2-carboxylic acid CAS 5408-39-9

Description

Compared with other compounds in its class, the molecular weight of 189.25 g/mol gives 3,4-Diphenylselenophene-2-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3,4-Diphenylselenophene-2-carboxylic acid (CAS 5408-39-9), molecular formula C12H15NO and molecular weight 189.25 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, 3,4-Diphenylselenophene-2-carboxylic acid is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 189.25 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 3,4-Diphenylselenophene-2-carboxylic 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.
