Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4390-16-3 Barbituric acid, monosodium salt 2,4,6(1H,3H,5H)-Pyrimidinetrione, monosodium salt Sodium barbiturate 2,4,6(1H,3H,5H)-Pyrimidinetrione, sodium salt (1:1) Barbituric acid, sodium salt EINECS 224-507-3 Monosodium barbiturate.

4390-16-3 Barbituric acid, monosodium salt 2,4,6(1H,3H,5H)-Pyrimidinetrione, monosodium salt Sodium barbiturate 2,4,6(1H,3H,5H)-Pyrimidinetrione, sodium salt (1:1) Barbituric acid, sodium salt EINECS 224-507-3 Monosodium barbiturate (CAS 4390-16-3), molecular formula C4H3N2O3Na and molecular weight 150.07 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 4390-16-3 Barbituric acid, monosodium salt 2,4,6(1H,3H,5H)-Pyrimidinetrione, monosodium salt Sodium barbiturate 2,4,6(1H,3H,5H)-Pyrimidinetrione, sodium salt (1:1) Barbituric acid, sodium salt EINECS 224-507-3 Monosodium barbiturate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 150.07 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.

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.
