2-Amino-4-((5-chloro-2,6-difluoropyrimidin-4-yl)amino)benzenesulfonic acid CAS 26592-28-9

Description

The occurrence of 2-Amino-4-((5-chloro-2,6-difluoropyrimidin-4-yl)amino)benzenesulfonic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Amino-4-((5-chloro-2,6-difluoropyrimidin-4-yl)amino)benzenesulfonic acid (CAS 26592-28-9) is a high-purity analytical reference standard with the molecular formula C10H7ClF2N4O3S and a molecular weight of 336.70 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 2-Amino-4-((5-chloro-2,6-difluoropyrimidin-4-yl)amino)benzenesulfonic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 336.70 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).

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.
