Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 127.10 g/mol gives 5-Aminofuran-2-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Aminofuran-2-carboxylic acid (CAS 341007-99-6) is a high-purity analytical reference standard with the molecular formula C5H5NO3 and a molecular weight of 127.10 g/mol.
Structurally, 5-Aminofuran-2-carboxylic acid (C5H5NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 127.10 g/mol, it falls into the low-molecular-weight range. 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.
