Description

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.

65813-53-8 3H4JM1983E 2-Phenylpropyl isobutyrate beta-Methylphenethyl isobutyrate Propanoic acid, 2-methyl-, 2-phenylpropyl ester EINECS 265-931-9 FEMA No. 2892 Hydratropyl isobutyrate Hydratropyl 2-methylpropanoate 2-Methyl-2-phenylethyl 2-methylpropanoate 2-Phenylpropyl 2-methylpropanoate UNII-3H4JM1983E (CAS 65813-53-8), molecular formula C13H24O2 and molecular weight 212.33 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 65813-53-8 3H4JM1983E 2-Phenylpropyl isobutyrate beta-Methylphenethyl isobutyrate Propanoic acid, 2-methyl-, 2-phenylpropyl ester EINECS 265-931-9 FEMA No. 2892 Hydratropyl isobutyrate Hydratropyl 2-methylpropanoate 2-Methyl-2-phenylethyl 2-methylpropanoate 2-Phenylpropyl 2-methylpropanoate UNII-3H4JM1983E is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 212.33 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.

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.
