Chemical Structure

Capecitabine Impurity 29 CAS 5006-64-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 150.11 g/mol gives Capecitabine Impurity 29 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Capecitabine Impurity 29 (CAS 5006-64-4) is a certified pharmaceutical impurity reference standard with the molecular formula C4H7FN2O3 and a molecular weight of 150.11 g/mol.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, Capecitabine Impurity 29 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 150.11 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 quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

CATO manufactures Capecitabine Impurity 29 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.
