Chemical Structure

1-Chloro-2-ethylbenzene CAS 89-96-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Chloro-2-ethylbenzene.

1-Chloro-2-ethylbenzene (CAS 89-96-3) is a high-purity analytical reference standard with the molecular formula C8H9Cl and a molecular weight of 140.61 g/mol.

Based on its molecular formula C8H9Cl, 1-Chloro-2-ethylbenzene contains chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 140.61 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 1-Chloro-2-ethylbenzene 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.
