Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Methyl-5-(pyrrolidin-1-ylmethyl)-1H-pyrazole-3-carboxylic acid.
1-Methyl-5-(pyrrolidin-1-ylmethyl)-1H-pyrazole-3-carboxylic acid (CAS 1223748-34-2) is a high-purity analytical reference standard with the molecular formula C10H15N3O2 and a molecular weight of 209.25 g/mol.
The molecular framework of 1-Methyl-5-(pyrrolidin-1-ylmethyl)-1H-pyrazole-3-carboxylic acid (C10H15N3O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
