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 trans-2-Methyl-3-(5’-carboxy-3’-methyl-2’-pentenyl)-1,4-naphthoquinone.
CATO supplies trans-2-Methyl-3-(5’-carboxy-3’-methyl-2’-pentenyl)-1,4-naphthoquinone (CAS 34185-71-2), a certified reference material (molecular formula C18H18O4, MW 298.33 g/mol) for analytical method development and quality control.
Structurally, trans-2-Methyl-3-(5’-carboxy-3’-methyl-2’-pentenyl)-1,4-naphthoquinone (C18H18O4) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 298.33 g/mol, it falls into the medium-molecular-weight range. 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.
