Chemical Structure
Description
CATO supplies 3,5-Dinitro-4-pyridinol (CAS 10425-71-5), a certified reference material (molecular formula C5H3N3O5, MW 185.09 g/mol) for analytical method development and quality control.
Structurally, 3,5-Dinitro-4-pyridinol (C5H3N3O5) contains a carbohydrate-derived structure, an amide group. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 185.09 g/mol, it falls into the medium-molecular-weight range. 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.
As a certified reference material (CRM), 3,5-Dinitro-4-pyridinol 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.
