Chemical Structure
Description
46L30W9XBB 33538-71-5 Venturicidin A Venturicidin B, 3'-carbamate A-130 AA-0368 EINECS 251-568-3 Venturidicin A UNII-46L30W9XBB (C41H67NO11) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
46L30W9XBB 33538-71-5 Venturicidin A Venturicidin B, 3'-carbamate A-130 AA-0368 EINECS 251-568-3 Venturidicin A UNII-46L30W9XBB (CAS 33538-71-5), molecular formula C41H67NO11 and molecular weight 749.97 g/mol, is a CATO reference standard with documented purity and traceability.
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.
