Chemical Structure

3-Bromopropyne CAS 106-96-7 chemical structure

Description

The occurrence of 3-Bromopropyne is closely related to bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-Bromopropyne (CAS 106-96-7), molecular formula C3H3Br and molecular weight 118.96 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-Bromopropyne (C3H3Br) is characterized by bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

CATO manufactures 3-Bromopropyne under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
