Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including trans-1-tert-butyl-2-[1-(2-methoxyethyl)-1H-pyrazol-4-yl]-5-oxopyrrolidine-3-carbonitrile.

trans-1-tert-butyl-2-[1-(2-methoxyethyl)-1H-pyrazol-4-yl]-5-oxopyrrolidine-3-carbonitrile (CAS 1808696-20-9), molecular formula C15H22N4O2 and molecular weight 290.36 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, trans-1-tert-butyl-2-[1-(2-methoxyethyl)-1H-pyrazol-4-yl]-5-oxopyrrolidine-3-carbonitrile (C15H22N4O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 290.36 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
