CATO supplies 2-methyl-oxazole-4-carboxylic acid methyl ester 2-methyl-oxazole-4-carboxylic aicd methyl ester 4-methyl-3,5-oxazolecarboxylic acid methyl ester 4-oxazolecarboxylic acid, 2-methyl-, methyl ester 4-oxazolecarboxylicacid,2-methyl-,methylester(9ci) 85806-67-3 Methyl 2-methyloxazole-4-carboxylate methyl 2-methyl-1,3-oxazole-4-carboxylate methyl-4-methyl-3,5-oxazolecarboxylate (CAS 85806-67-3), a certified reference material (molecular formula C6H11NO3, MW 145.16 g/mol) for analytical method development and quality control.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 2-methyl-oxazole-4-carboxylic acid methyl ester 2-methyl-oxazole-4-carboxylic aicd methyl ester 4-methyl-3,5-oxazolecarboxylic acid methyl ester 4-oxazolecarboxylic acid, 2-methyl-, methyl ester 4-oxazolecarboxylicacid,2-methyl-,methylester(9ci) 85806-67-3 Methyl 2-methyloxazole-4-carboxylate methyl 2-methyl-1,3-oxazole-4-carboxylate methyl-4-methyl-3,5-oxazolecarboxylate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 145.16 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.
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.
