Chemical Structure
Description
2-Amino-5-chloro-3-iodopyridine 211308-81-5 MFCD07644578 SY041328 (CAS 211308-81-5), molecular formula C5H10ClIN2 and molecular weight 260.50 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to chlorine/iodine substitution, 2-Amino-5-chloro-3-iodopyridine 211308-81-5 MFCD07644578 SY041328 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 260.50 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
