2-((7-Nitrobenzo[c][1,2,5]oxadiazol-4-yl)thio)acetic acid CAS 18333-81-8 chemical structure

Description

The occurrence of 2-((7-Nitrobenzo[c][1,2,5]oxadiazol-4-yl)thio)acetic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2-((7-Nitrobenzo[c][1,2,5]oxadiazol-4-yl)thio)acetic acid (CAS 18333-81-8), a certified reference material (molecular formula C8H5N3O5S, MW 255.21 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-((7-Nitrobenzo[c][1,2,5]oxadiazol-4-yl)thio)acetic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 255.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 2-((7-Nitrobenzo[c][1,2,5]oxadiazol-4-yl)thio)acetic acid 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.
