Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 194.23 g/mol gives N-Isobutyl-2-nitroaniline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies N-Isobutyl-2-nitroaniline (CAS 55432-22-9), a certified reference material (molecular formula C10H14N2O2, MW 194.23 g/mol) for analytical method development and quality control.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, N-Isobutyl-2-nitroaniline is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 194.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 N-Isobutyl-2-nitroaniline 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.
