The occurrence of 875-97-8 70M59F803X 2,4-Dioxo-5-thiazolidineacetic acid UNII-70M59F803X 5-Thiazolidineacetic acid, 2,4-dioxo- (2,4-Dioxothiazolidin-5-yl)acetic acid 5-Thiazoleacetic acid, 2,3-dihydro-4-hydroxy-2-oxo- 5-Thiazoleacetic acid, 2,4-dihydroxy- 2,3-Dihydro-4-hydroxy-2-oxo-5-thiazoleacetic acid 2-(2,4-Dihydroxythiazol-5-yl)acetic acid NSC-60548 is closely related to a carbohydrate-derived structure, an amide group, a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
875-97-8 70M59F803X 2,4-Dioxo-5-thiazolidineacetic acid UNII-70M59F803X 5-Thiazolidineacetic acid, 2,4-dioxo- (2,4-Dioxothiazolidin-5-yl)acetic acid 5-Thiazoleacetic acid, 2,3-dihydro-4-hydroxy-2-oxo- 5-Thiazoleacetic acid, 2,4-dihydroxy- 2,3-Dihydro-4-hydroxy-2-oxo-5-thiazoleacetic acid 2-(2,4-Dihydroxythiazol-5-yl)acetic acid NSC-60548 (CAS 875-97-8) is a high-purity analytical reference standard with the molecular formula C5H5NO4S and a molecular weight of 175.16 g/mol.
Owing to a carbohydrate-derived structure, an amide group, a sulfone group, 875-97-8 70M59F803X 2,4-Dioxo-5-thiazolidineacetic acid UNII-70M59F803X 5-Thiazolidineacetic acid, 2,4-dioxo- (2,4-Dioxothiazolidin-5-yl)acetic acid 5-Thiazoleacetic acid, 2,3-dihydro-4-hydroxy-2-oxo- 5-Thiazoleacetic acid, 2,4-dihydroxy- 2,3-Dihydro-4-hydroxy-2-oxo-5-thiazoleacetic acid 2-(2,4-Dihydroxythiazol-5-yl)acetic acid NSC-60548 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 175.16 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.
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.
