2-(((4-Hydroxy-6-isopropylthieno[2,3-d]pyrimidin-2-yl)methyl)thio)acetic acid CAS 1144489-45-1

Description

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.

2-(((4-Hydroxy-6-isopropylthieno[2,3-d]pyrimidin-2-yl)methyl)thio)acetic acid (CAS 1144489-45-1), molecular formula C12H14N2O3S2 and molecular weight 298.38 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(((4-Hydroxy-6-isopropylthieno[2,3-d]pyrimidin-2-yl)methyl)thio)acetic acid (C12H14N2O3S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
