Description
CATO supplies 5-(2,3,4-Trimethoxyphenyl)-1,3,4-thiadiazol-2-amine (CAS 299932-72-2), a certified reference material (molecular formula C11H13N3O3S, MW 267.30 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 5-(2,3,4-Trimethoxyphenyl)-1,3,4-thiadiazol-2-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 267.30 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.
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.
