Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (1S,2R)-Methyl 2-(2-(tert-butoxy)-2-oxoethyl)cyclopropanecarboxylate.
CATO supplies (1S,2R)-Methyl 2-(2-(tert-butoxy)-2-oxoethyl)cyclopropanecarboxylate (CAS 79252-64-5), a certified reference material (molecular formula C11H18O4, MW 214.26 g/mol) for analytical method development and quality control.
Structurally, (1S,2R)-Methyl 2-(2-(tert-butoxy)-2-oxoethyl)cyclopropanecarboxylate (C11H18O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 214.26 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
