This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

4,5,6,7-Tetrahydro-1H-pyrazolo[4,3-c]pyridin-3-carboxylic acid hydrochloride 933689-86-2 FS-6394 (CAS 933689-86-2), molecular formula C7H13N3O2 and molecular weight 171.20 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4,5,6,7-Tetrahydro-1H-pyrazolo[4,3-c]pyridin-3-carboxylic acid hydrochloride 933689-86-2 FS-6394 (C7H13N3O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 171.20 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
