Chemical Structure

1,2,4-Trimethylcyclopenta-1,3-diene CAS 4784-94-5 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

1,2,4-Trimethylcyclopenta-1,3-diene (CAS 4784-94-5), molecular formula C8H12 and molecular weight 108.18 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an organic framework, 1,2,4-Trimethylcyclopenta-1,3-diene is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 108.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

CATO manufactures 1,2,4-Trimethylcyclopenta-1,3-diene 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.
