1-(3-Nitro-4-{2-[(1Z)-1,2,3,4-tetrahydronaphthalen-1-ylidene]hydrazin-1-yl}benzenesulfonyl)piperidine-4-carboxylic acid CAS 866142-50-9

Description

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 1-(3-Nitro-4-{2-[(1Z)-1,2,3,4-tetrahydronaphthalen-1-ylidene]hydrazin-1-yl}benzenesulfonyl)piperidine-4-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 472.51 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).

1-(3-Nitro-4-{2-[(1Z)-1,2,3,4-tetrahydronaphthalen-1-ylidene]hydrazin-1-yl}benzenesulfonyl)piperidine-4-carboxylic acid (CAS 866142-50-9), molecular formula C22H24N4O6S and molecular weight 472.51 g/mol, is a CATO reference standard with documented purity and traceability.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
