Description

Compared with other compounds in its class, the molecular weight of 147.13 g/mol gives 1H-Pyrazolo[4,3-b]pyridine-3-carbaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1H-Pyrazolo[4,3-b]pyridine-3-carbaldehyde (CAS 1286754-05-9), molecular formula C7H5N3O and molecular weight 147.13 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system, 1H-Pyrazolo[4,3-b]pyridine-3-carbaldehyde is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 147.13 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.
