Chemical Structure
Description
The occurrence of tert-Butyl 3-(2-ethynylphenyl)propanoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies tert-Butyl 3-(2-ethynylphenyl)propanoate (CAS 2502187-84-8), a certified reference material (molecular formula C15H18O2, MW 230.30 g/mol) for analytical method development and quality control.
Structurally, tert-Butyl 3-(2-ethynylphenyl)propanoate (C15H18O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 230.30 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
