Chemical Structure

2,7-Dimethoxy-3,6-bis(methyltelluro)-naphthalene CAS 105405-04-7 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 2,7-Dimethoxy-3,6-bis(methyltelluro)-naphthalene.

2,7-Dimethoxy-3,6-bis(methyltelluro)-naphthalene (CAS 105405-04-7), molecular formula C14H16O2Te2 and molecular weight 471.48 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2,7-Dimethoxy-3,6-bis(methyltelluro)-naphthalene (C14H16O2Te2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 471.48 g/mol, it falls into the moderately-high-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.

As a certified reference material (CRM), 2,7-Dimethoxy-3,6-bis(methyltelluro)-naphthalene 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.
