Chemical Structure
Description
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.
CATO supplies Ethyl 3-hydroxy-2,2,3-trimethylbutanoate (CAS 62817-86-1), a certified reference material (molecular formula C9H18O3, MW 174.24 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Ethyl 3-hydroxy-2,2,3-trimethylbutanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 174.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
