Chemical Structure
Description
J51 (CAS 1393529-03-7) is a high-purity analytical reference standard with the molecular formula C74H99F2N3S6N and a molecular weight of 1274.99 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution, J51 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1274.99 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), J51 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.
