Chemical Structure
Description
CATO supplies 1S-cis-Decamethrinic Acid (CAS 72691-18-0), a certified reference material (molecular formula C8H10Br2O2, MW 297.97 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, 1S-cis-Decamethrinic Acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 297.97 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).
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), 1S-cis-Decamethrinic 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.
