Adenosine Impurity 28 CAS 162660-35-7

Description

Compared with other compounds in its class, the molecular weight of 395.33 g/mol gives Adenosine Impurity 28 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Adenosine Impurity 28 (CAS 162660-35-7), a pharmacopoeial impurity reference standard (molecular formula C16H18N3[15N]O8, MW 395.33 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Adenosine Impurity 28 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 395.33 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.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

CATO manufactures Adenosine Impurity 28 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.
