Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 324.37 g/mol gives Bestatin Impurity 19 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Bestatin Impurity 19 (CAS 70267-76-4), molecular formula C16H24N2O5 and molecular weight 324.37 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Bestatin Impurity 19 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 324.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures Bestatin Impurity 19 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
