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 (R)-2,3;4,5-Bis(1,2,3- phenylnaphtho)-1,6,9,12,15,18-hexaoxacycloeicosa-2,4-diene.
(R)-2,3;4,5-Bis(1,2,3- phenylnaphtho)-1,6,9,12,15,18-hexaoxacycloeicosa-2,4-diene (CAS 75684-74-1), molecular formula C42H40O6 and molecular weight 640.76 g/mol, is a CATO reference standard with documented purity and traceability.
(R)-2,3;4,5-Bis(1,2,3- phenylnaphtho)-1,6,9,12,15,18-hexaoxacycloeicosa-2,4-diene (C42H40O6) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
