Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Tetrabutylphosphonium acetate.
Tetrabutylphosphonium acetate (CAS 30345-49-4), molecular formula C24H40O5 and molecular weight 408.57 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, a hydroxyl group, an ether linkage, Tetrabutylphosphonium acetate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 408.57 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), Tetrabutylphosphonium acetate 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.
