Chemical Structure
Description
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.
4-Amino-5-oxotetrahydrofuran-2-carboxylic acid (CAS 150576-56-0) is a high-purity analytical reference standard with the molecular formula C5H7NO4 and a molecular weight of 145.11 g/mol.
Owing to a carbohydrate-derived structure, an amide group, 4-Amino-5-oxotetrahydrofuran-2-carboxylic acid is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 145.11 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
