Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Hydroxy-1,2-dimethylpyridin-1-ium iodide.
5-Hydroxy-1,2-dimethylpyridin-1-ium iodide (CAS 59344-35-3), molecular formula IC7H10NO and molecular weight 251.06 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5-Hydroxy-1,2-dimethylpyridin-1-ium iodide (IC7H10NO) contains an amide group, a hydroxyl group, an ether linkage, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 251.06 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
CATO manufactures 5-Hydroxy-1,2-dimethylpyridin-1-ium iodide 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.
