N5-[Imino[[(4-methylphenyl)sulfonyl]amino]methyl]-D-ornithine CAS 97233-92-6

Description

As a certified reference material (CRM), N5-[Imino[[(4-methylphenyl)sulfonyl]amino]methyl]-D-ornithine 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.

N5-[Imino[[(4-methylphenyl)sulfonyl]amino]methyl]-D-ornithine (CAS 97233-92-6), molecular formula C13H20N4O4S and molecular weight 328.39 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, N5-[Imino[[(4-methylphenyl)sulfonyl]amino]methyl]-D-ornithine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 328.39 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.
