7-Chloroisochromane CAS 22901-73-1 chemical structure

Description

CATO manufactures 7-Chloroisochromane 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.

CATO supplies 7-Chloroisochromane (CAS 22901-73-1), a certified reference material (molecular formula C9H9ClO, MW 168.62 g/mol) for analytical method development and quality control.

Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 7-Chloroisochromane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 168.62 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.
