Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2,4-difluorophenyl)hydrazine.
(2,4-difluorophenyl)hydrazine (CAS 40594-30-7) is a high-purity analytical reference standard with the molecular formula C6H6F2N2 and a molecular weight of 144.12 g/mol.
Owing to a nitrile group, fluorine substitution, an aromatic ring system, (2,4-difluorophenyl)hydrazine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.12 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).
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), (2,4-difluorophenyl)hydrazine 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.
