Description
0167AD 1185175-77-2 2-(2-Pyrazol-1-yl-ethoxy)-phenylaminehydrochloride C11H14ClN3O (CAS 1185175-77-2), molecular formula C11H13N3OHCl and molecular weight 239.70 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 0167AD 1185175-77-2 2-(2-Pyrazol-1-yl-ethoxy)-phenylaminehydrochloride C11H14ClN3O (C11H13N3OHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 239.70 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
