Description
CATO manufactures 1-Amino-1H-pyrrole-2,5-dione 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.
1-Amino-1H-pyrrole-2,5-dione (CAS 37770-94-8), molecular formula C11H20Cl3NO2 and molecular weight 304.64 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Amino-1H-pyrrole-2,5-dione (C11H20Cl3NO2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
