3-Tert-butyl-1-ethyl-1h-pyrazole-4-carbaldehyde CAS 1249396-42-6

Description

The occurrence of 3-Tert-butyl-1-ethyl-1h-pyrazole-4-carbaldehyde is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-Tert-butyl-1-ethyl-1h-pyrazole-4-carbaldehyde (CAS 1249396-42-6), molecular formula C10H16N2O and molecular weight 180.25 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-Tert-butyl-1-ethyl-1h-pyrazole-4-carbaldehyde (C10H16N2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
