Chemical Structure
Description
The molecular framework of 3-(4-Chloro-3-ethyl-1-methyl-1h-pyrazol-5-yl)propan-1-ol (C9H15ClN2O) is characterized by an amide 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
3-(4-Chloro-3-ethyl-1-methyl-1h-pyrazol-5-yl)propan-1-ol (CAS 1465040-30-5), molecular formula C9H15ClN2O and molecular weight 202.68 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.
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.
