Chemical Structure
Description
The molecular framework of 1-(2,3-dihydroxypropyl)-1H-pyrazole-4-carboxylic acid hydrochloride (C7H10N2O4HCl) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
1-(2,3-dihydroxypropyl)-1H-pyrazole-4-carboxylic acid hydrochloride (CAS 1864073-63-1), molecular formula C7H10N2O4HCl and molecular weight 222.62 g/mol, is a CATO reference standard with documented purity and traceability.
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.
As a certified reference material (CRM), 1-(2,3-dihydroxypropyl)-1H-pyrazole-4-carboxylic acid hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
