Chemical Structure
Description
As a certified reference material (CRM), 3-((5-Methyl-3-nitro-1H-pyrazol-1-yl)methoxy)benzaldehyde meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
3-((5-Methyl-3-nitro-1H-pyrazol-1-yl)methoxy)benzaldehyde (CAS 1006435-99-9), molecular formula C12H11N3O4 and molecular weight 261.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-((5-Methyl-3-nitro-1H-pyrazol-1-yl)methoxy)benzaldehyde (C12H11N3O4) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
