Gemcitabine Impurity 18 CAS 139729-89-8

Description

The occurrence of Gemcitabine Impurity 18 is closely related to a carbohydrate-derived structure, an amide group, a phosphate ester group, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Gemcitabine Impurity 18 (CAS 139729-89-8), a certified reference material (molecular formula C9H11F2N2O8P, MW 344.16 g/mol) for analytical method development and quality control.

The molecular framework of Gemcitabine Impurity 18 (C9H11F2N2O8P) is characterized by a carbohydrate-derived structure, an amide group, a phosphate ester group, fluorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 Gemcitabine Impurity 18 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.
