Chemical Structure

Cefonicid Disodium Salt CAS 190181-58-9 chemical structure

Description

Cefonicid Disodium Salt (CAS 190181-58-9) is a high-purity analytical reference standard with the molecular formula C18H16N6O8S3Na and a molecular weight of 563.53 g/mol.

Based on its molecular formula C18H16N6O8S3Na, Cefonicid Disodium Salt contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 563.53 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
