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 3,4-Dichloronaphthalen-1-ol.
3,4-Dichloronaphthalen-1-ol (CAS 58877-90-0), molecular formula C29H18O6 and molecular weight 462.45 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3,4-Dichloronaphthalen-1-ol (C29H18O6) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 21.0, corresponding to approximately 21 ring(s) or double-bond equivalent(s). With a molecular weight of 462.45 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), 3,4-Dichloronaphthalen-1-ol 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.
