1-Cyclopentyl-2,5-dimethyl-1H-pyrrole-3-carbaldehyde CAS 326916-19-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Cyclopentyl-2,5-dimethyl-1H-pyrrole-3-carbaldehyde.

1-Cyclopentyl-2,5-dimethyl-1H-pyrrole-3-carbaldehyde (CAS 326916-19-2) is a high-purity analytical reference standard with the molecular formula C12H17NO and a molecular weight of 191.27 g/mol.

Structurally, 1-Cyclopentyl-2,5-dimethyl-1H-pyrrole-3-carbaldehyde (C12H17NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 191.27 g/mol, it falls into the medium-molecular-weight range. 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.
