Chemical Structure

Tert-butyl (E)-4-acetoxybut-2-enoate CAS 902154-51-2 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Tert-butyl (E)-4-acetoxybut-2-enoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 200.23 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.

CATO supplies Tert-butyl (E)-4-acetoxybut-2-enoate (CAS 902154-51-2), a certified reference material (molecular formula C10H16O4, MW 200.23 g/mol) for analytical method development and quality control.

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.
