Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1142202-88-7 9288AC C13H13N3O4S2 {[(5-{[(4-Methoxyphenyl)amino]carbonyl}-1,3,4-thiadiazol-2-yl)methyl]thio}acetic acid.
CATO supplies 1142202-88-7 9288AC C13H13N3O4S2 {[(5-{[(4-Methoxyphenyl)amino]carbonyl}-1,3,4-thiadiazol-2-yl)methyl]thio}acetic acid (CAS 1142202-88-7), a certified reference material (molecular formula C13H13N3O4S2, MW 339.39 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, 1142202-88-7 9288AC C13H13N3O4S2 {[(5-{[(4-Methoxyphenyl)amino]carbonyl}-1,3,4-thiadiazol-2-yl)methyl]thio}acetic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 339.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
