Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 1877.64 g/mol gives Teicoplanin A2-1 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Teicoplanin A2-1 (CAS 91032-34-7), molecular formula C88H95Cl2N9O33 and molecular weight 1877.64 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Teicoplanin A2-1 (C88H95Cl2N9O33) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
