5-Fluorocytosine CAS 2022-85-7 chemical structure

Description

CATO supplies 5-Fluorocytosine (CAS 2022-85-7), a certified reference material (molecular formula C4H4FN3O, MW 129.09 g/mol) for analytical method development and quality control.

5-Fluorocytosine (C4H4FN3O) contains an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point; 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.

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 5-Fluorocytosine 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.
