Chemical Structure

tert-Butyl 4,4-difluorobut-2-enoate CAS 1909358-86-6 chemical structure

Description

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.

tert-Butyl 4,4-difluorobut-2-enoate (CAS 1909358-86-6), molecular formula C8H12F2O2 and molecular weight 178.18 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, tert-Butyl 4,4-difluorobut-2-enoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 178.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO manufactures tert-Butyl 4,4-difluorobut-2-enoate 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.
