Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 323.08 g/mol gives Ethyl 2,4-dihydroxy-5-iodo-6-methylnicotinate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 2,4-dihydroxy-5-iodo-6-methylnicotinate (CAS 846569-82-2) is a high-purity analytical reference standard with the molecular formula C9H10INO4 and a molecular weight of 323.08 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution, Ethyl 2,4-dihydroxy-5-iodo-6-methylnicotinate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 323.08 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.
As a certified reference material (CRM), Ethyl 2,4-dihydroxy-5-iodo-6-methylnicotinate 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.
