Chemical Structure

Famphur Impurity 5 CAS 3078-97-5 chemical structure

Description

Famphur Impurity 5 (C12H20NO5PS2) contains an amide group, a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.

Famphur Impurity 5 (CAS 3078-97-5) is a high-purity analytical reference standard with the molecular formula C12H20NO5PS2 and a molecular weight of 353.39 g/mol.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures Famphur Impurity 5 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.
