Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 4833-56-1 1874G25H4S Homopteroic acid 4-((2-(2-Amino-1,4-dihydro-4-oxo-6-pteridinyl)ethyl)amino)benzoic acid NSC 77011 UNII-1874G25H4S is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 326.31 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).
CATO supplies 4833-56-1 1874G25H4S Homopteroic acid 4-((2-(2-Amino-1,4-dihydro-4-oxo-6-pteridinyl)ethyl)amino)benzoic acid NSC 77011 UNII-1874G25H4S (CAS 4833-56-1), a certified reference material (molecular formula C15H14N6O3, MW 326.31 g/mol) for analytical method development and quality control.
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.
