6-Chloro-10,13-dioxa-4-thiatricyclo[7.4.0.0,3,7]trideca-1(9),2,5,7-tetraene-5-carboxylic acid CAS 854357-34-9

Description

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

6-Chloro-10,13-dioxa-4-thiatricyclo[7.4.0.0,3,7]trideca-1(9),2,5,7-tetraene-5-carboxylic acid (CAS 854357-34-9) is a high-purity analytical reference standard with the molecular formula C11H7ClO4S and a molecular weight of 270.69 g/mol.

The molecular framework of 6-Chloro-10,13-dioxa-4-thiatricyclo[7.4.0.0,3,7]trideca-1(9),2,5,7-tetraene-5-carboxylic acid (C11H7ClO4S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 6-Chloro-10,13-dioxa-4-thiatricyclo[7.4.0.0,3,7]trideca-1(9),2,5,7-tetraene-5-carboxylic acid 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.
