Description
As a certified reference material (CRM), 5-Isopropyl-2-methylpyridine 1-oxide 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.
5-Isopropyl-2-methylpyridine 1-oxide (CAS 134923-06-1) is a high-purity analytical reference standard with the molecular formula C9H13NO and a molecular weight of 151.21 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 5-Isopropyl-2-methylpyridine 1-oxide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 151.21 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).
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.
