Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-tert-butyl-2-[1-(2-methoxyethyl)-1H-pyrazol-4-yl]-5-oxopyrrolidine-3-carboxylic acid.
CATO supplies 1-tert-butyl-2-[1-(2-methoxyethyl)-1H-pyrazol-4-yl]-5-oxopyrrolidine-3-carboxylic acid (CAS 1795305-12-2), a certified reference material (molecular formula C15H23N3O4, MW 309.36 g/mol) for analytical method development and quality control.
Structurally, 1-tert-butyl-2-[1-(2-methoxyethyl)-1H-pyrazol-4-yl]-5-oxopyrrolidine-3-carboxylic acid (C15H23N3O4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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 309.36 g/mol, it falls into the moderately-high-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).
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-tert-butyl-2-[1-(2-methoxyethyl)-1H-pyrazol-4-yl]-5-oxopyrrolidine-3-carboxylic acid 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.
