Chemical Structure
Description
Structurally, 1-ethynyl-2-methylbenzene 2-Ethynyltoluene 766-47-2 A15798 (C9H14) contains an organic framework. 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 122.21 g/mol, it falls into the low-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO supplies 1-ethynyl-2-methylbenzene 2-Ethynyltoluene 766-47-2 A15798 (CAS 766-47-2), a certified reference material (molecular formula C9H14, MW 122.21 g/mol) for analytical method development and quality control.
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.
