Chemical Structure
Description
The occurrence of 1-(3-Bromo-1-propyn-1-yl)-4-methyl-benzene is closely related to bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1-(3-Bromo-1-propyn-1-yl)-4-methyl-benzene (CAS 130024-90-7), a certified reference material (molecular formula C10H9Br, MW 209.08 g/mol) for analytical method development and quality control.
Structurally, 1-(3-Bromo-1-propyn-1-yl)-4-methyl-benzene (C10H9Br) contains bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 209.08 g/mol, it falls into the medium-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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
