Description

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.

7477-13-6 InChI=1/C6H4N4O2/c11-6(12)4-1-2-5-7-8-9-10(5)3-4/h1-3H,(H,11,12 (CAS 7477-13-6), molecular formula C6H4N4O2 and molecular weight 164.12 g/mol, is a CATO reference standard with documented purity and traceability.

7477-13-6 InChI=1/C6H4N4O2/c11-6(12)4-1-2-5-7-8-9-10(5)3-4/h1-3H,(H,11,12 (C6H4N4O2) contains an amino-acid-derived structure, an amide 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures 7477-13-6 InChI=1/C6H4N4O2/c11-6(12)4-1-2-5-7-8-9-10(5)3-4/h1-3H,(H,11,12 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.
