Chemical Structure
Description
CATO supplies [4-(1H-Tetrazol-1-yl)phenoxy]acetic acid (CAS 832740-47-3), a certified reference material (molecular formula C9H8N4O3, MW 220.18 g/mol) for analytical method development and quality control.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, [4-(1H-Tetrazol-1-yl)phenoxy]acetic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 220.18 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), [4-(1H-Tetrazol-1-yl)phenoxy]acetic 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.
