Chemical Structure

Lefamulin Acetate CAS 1350636-82-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 567.78 g/mol gives Lefamulin Acetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Lefamulin Acetate (CAS 1350636-82-6), a certified reference material (molecular formula C28H45NO5SC2H4O2, MW 567.78 g/mol) for analytical method development and quality control.

Structurally, Lefamulin Acetate (C28H45NO5SC2H4O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 567.78 g/mol, it falls into the moderately-high-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.
