Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,1,4,4,6-Pentamethyl-7-(1-(p-tolyl)vinyl)-1,2,3,4-tetrahydronaphthalene.
CATO supplies 1,1,4,4,6-Pentamethyl-7-(1-(p-tolyl)vinyl)-1,2,3,4-tetrahydronaphthalene (CAS 1688656-72-5), a certified reference material (molecular formula C24H30, MW 318.50 g/mol) for analytical method development and quality control.
1,1,4,4,6-Pentamethyl-7-(1-(p-tolyl)vinyl)-1,2,3,4-tetrahydronaphthalene (C24H30) contains a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 1,1,4,4,6-Pentamethyl-7-(1-(p-tolyl)vinyl)-1,2,3,4-tetrahydronaphthalene 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.
