1-nitroso-1H-pyrrole-2-carbaldehyde CAS CATO-C4X-194625 chemical structure

Description

CATO manufactures 1-nitroso-1H-pyrrole-2-carbaldehyde 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-nitroso-1H-pyrrole-2-carbaldehyde (CAS CATO-C4X-194625) is a high-purity analytical reference standard with the molecular formula C5H4N2O2 and a molecular weight of 124.10 g/mol.

1-nitroso-1H-pyrrole-2-carbaldehyde (C5H4N2O2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
