Chemical Structure

(S)-4-Chlorostyrene Oxide CAS 97466-49-4 chemical structure

Description

CATO supplies (S)-4-Chlorostyrene Oxide (CAS 97466-49-4), a certified reference material (molecular formula C8H7ClO, MW 154.59 g/mol) for analytical method development and quality control.

Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, (S)-4-Chlorostyrene Oxide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 154.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), (S)-4-Chlorostyrene Oxide 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.
