Chemical Structure

3-(2-nitroethyl)thiophene CAS 30807-45-5 chemical structure

Description

3-(2-nitroethyl)thiophene (CAS 30807-45-5) is a high-purity analytical reference standard with the molecular formula C6H7NO2S and a molecular weight of 157.19 g/mol.

3-(2-nitroethyl)thiophene (C6H7NO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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), 3-(2-nitroethyl)thiophene 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.
