Description

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

3549-23-3 8A4H5QO9OJ Methyl p-tert-butylphenylacetate Benzeneacetic acid, 4-(1,1-dimethylethyl)-, methyl ester Methyl 4-tert-butylphenylacetate Acetic acid, (p-tert-butylphenyl)-, methyl ester EINECS 222-602-4 FEMA No. 2690 Methyl 4-(1,1-dimethylethyl)benzeneacetate UNII-8A4H5QO9OJ (CAS 3549-23-3) is a high-purity analytical reference standard with the molecular formula C13H24O2 and a molecular weight of 212.33 g/mol.

The molecular framework of 3549-23-3 8A4H5QO9OJ Methyl p-tert-butylphenylacetate Benzeneacetic acid, 4-(1,1-dimethylethyl)-, methyl ester Methyl 4-tert-butylphenylacetate Acetic acid, (p-tert-butylphenyl)-, methyl ester EINECS 222-602-4 FEMA No. 2690 Methyl 4-(1,1-dimethylethyl)benzeneacetate UNII-8A4H5QO9OJ (C13H24O2) is characterized by a carboxylic acid 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.

As a certified reference material (CRM), 3549-23-3 8A4H5QO9OJ Methyl p-tert-butylphenylacetate Benzeneacetic acid, 4-(1,1-dimethylethyl)-, methyl ester Methyl 4-tert-butylphenylacetate Acetic acid, (p-tert-butylphenyl)-, methyl ester EINECS 222-602-4 FEMA No. 2690 Methyl 4-(1,1-dimethylethyl)benzeneacetate UNII-8A4H5QO9OJ 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.
