Chemical Structure

Trans polyisoprene CAS 104389-32-4 chemical structure

Description

The occurrence of Trans polyisoprene is closely related to an organic framework in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Trans polyisoprene (CAS 104389-32-4), a certified reference material (molecular formula C5H8, MW 68.12 g/mol) for analytical method development and quality control.

Owing to an organic framework, Trans polyisoprene is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 68.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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), Trans polyisoprene 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.
