(1-(4-Ethylphenyl)-2,5-dimethyl-1H-pyrrol-3-yl)methanol CAS 678550-05-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (1-(4-Ethylphenyl)-2,5-dimethyl-1H-pyrrol-3-yl)methanol.

(1-(4-Ethylphenyl)-2,5-dimethyl-1H-pyrrol-3-yl)methanol (CAS 678550-05-5), molecular formula C15H19NO and molecular weight 229.32 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, (1-(4-Ethylphenyl)-2,5-dimethyl-1H-pyrrol-3-yl)methanol is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 229.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
