N'-Isopropylidene-2-nitrobenzenesulfonohydrazide CAS 6655-27-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N'-Isopropylidene-2-nitrobenzenesulfonohydrazide.

N'-Isopropylidene-2-nitrobenzenesulfonohydrazide (CAS 6655-27-2) is a high-purity analytical reference standard with the molecular formula C9H11N3O4S and a molecular weight of 257.27 g/mol.

N'-Isopropylidene-2-nitrobenzenesulfonohydrazide (C9H11N3O4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), N'-Isopropylidene-2-nitrobenzenesulfonohydrazide 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.
