Description

The occurrence of 5-Formylthiophene-2-boronic acid 5-formylthiophen-2-boronic acid 5-formyl-2-thiopheneboronic acid 2-formylthiophene-5-boronic acid 2-formyl thiophene-5-boronic acid 5-formylthienyl-2-boronic acid 5-formylthiophen-1-boronic acid 5-formylthien-2-ylboronic acid 5-carbaldehyde-2-thiophenboronic acid 5-Formyl-2-thienylboronic acid 4347-33-5 is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Formylthiophene-2-boronic acid 5-formylthiophen-2-boronic acid 5-formyl-2-thiopheneboronic acid 2-formylthiophene-5-boronic acid 2-formyl thiophene-5-boronic acid 5-formylthienyl-2-boronic acid 5-formylthiophen-1-boronic acid 5-formylthien-2-ylboronic acid 5-carbaldehyde-2-thiophenboronic acid 5-Formyl-2-thienylboronic acid 4347-33-5 (CAS 4347-33-5), molecular formula C5H9BO3S and molecular weight 160.00 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C5H9BO3S, 5-Formylthiophene-2-boronic acid 5-formylthiophen-2-boronic acid 5-formyl-2-thiopheneboronic acid 2-formylthiophene-5-boronic acid 2-formyl thiophene-5-boronic acid 5-formylthienyl-2-boronic acid 5-formylthiophen-1-boronic acid 5-formylthien-2-ylboronic acid 5-carbaldehyde-2-thiophenboronic acid 5-Formyl-2-thienylboronic acid 4347-33-5 contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 160.00 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
