Description

CATO manufactures Spiro[4H-cyclohepta[2,1-a:3,4-a′]dinaphthalene-4,1′-[2,4]cyclopentadiene], 3,5-dihydro-, (S)- under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

CATO supplies Spiro[4H-cyclohepta[2,1-a:3,4-a′]dinaphthalene-4,1′-[2,4]cyclopentadiene], 3,5-dihydro-, (S)- (CAS 125443-42-7), a certified reference material (molecular formula C27H20, MW 344.45 g/mol) for analytical method development and quality control.

Owing to a polycyclic aromatic system, Spiro[4H-cyclohepta[2,1-a:3,4-a′]dinaphthalene-4,1′-[2,4]cyclopentadiene], 3,5-dihydro-, (S)- is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 344.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
