Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 253.21 g/mol gives Trimethyl pyridine-2,4,6-tricarboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Trimethyl pyridine-2,4,6-tricarboxylate (CAS 25309-39-1), molecular formula C11H11NO6 and molecular weight 253.21 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Trimethyl pyridine-2,4,6-tricarboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 253.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
