2-Hydroxyisonicotinaldehyde CAS 188554-13-4

Description

Compared with other compounds in its class, the molecular weight of 123.11 g/mol gives 2-Hydroxyisonicotinaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-Hydroxyisonicotinaldehyde (CAS 188554-13-4), a certified reference material (molecular formula C6H5NO2, MW 123.11 g/mol) for analytical method development and quality control.

Structurally, 2-Hydroxyisonicotinaldehyde (C6H5NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 123.11 g/mol, it falls into the low-molecular-weight range. 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.
