2-Bromo-5-methyl-3-nitrothiophene CAS 82834-45-5

Description

The occurrence of 2-Bromo-5-methyl-3-nitrothiophene is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Bromo-5-methyl-3-nitrothiophene (CAS 82834-45-5) is a high-purity analytical reference standard with the molecular formula C5H4BrNO2S and a molecular weight of 222.06 g/mol.

Based on its molecular formula C5H4BrNO2S, 2-Bromo-5-methyl-3-nitrothiophene contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 222.06 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
