2-((2-Nitrophenyl)thio)acetaldehyde CAS 721448-72-2

Description

The occurrence of 2-((2-Nitrophenyl)thio)acetaldehyde is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2-((2-Nitrophenyl)thio)acetaldehyde (CAS 721448-72-2), a certified reference material (molecular formula C8H7NO3S, MW 197.21 g/mol) for analytical method development and quality control.

2-((2-Nitrophenyl)thio)acetaldehyde (C8H7NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
