Chemical Structure
Description
The molecular framework of Isobutene (ca. 15% in Tetrahydrofuran) (C4H8) is characterized by an organic framework. In reversed-phase chromatography, its retention is governed primarily by its non-polar molecular character, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
Isobutene (ca. 15% in Tetrahydrofuran) (CAS 115-11-7), molecular formula C4H8 and molecular weight 56.11 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Isobutene (ca. 15% in Tetrahydrofuran) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
