Chemical Structure

Novobiocin Sodium Salt CAS 1476-53-5 chemical structure

Description

Novobiocin Sodium Salt (CAS 1476-53-5) is a high-purity analytical reference standard with the molecular formula C31H35N2NaO11 and a molecular weight of 634.61 g/mol.

Based on its molecular formula C31H35N2NaO11, Novobiocin Sodium Salt contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 634.61 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
