Description

Structurally, 1,2,3,4,6,7,8,9,12,12,13,13-Dodecachloro-4,4a,4b,5,5a,6,9,9a,10,10a,11,11a-dodecahydro-1,4:6,9-dimethano-1H-benzo[b]fluorene 58910-85-3 Fireshield C2 (C19H12Cl12) contains chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 665.73 g/mol, it falls into the high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

1,2,3,4,6,7,8,9,12,12,13,13-Dodecachloro-4,4a,4b,5,5a,6,9,9a,10,10a,11,11a-dodecahydro-1,4:6,9-dimethano-1H-benzo[b]fluorene 58910-85-3 Fireshield C2 (CAS 58910-85-3) is a high-purity analytical reference standard with the molecular formula C19H12Cl12 and a molecular weight of 665.73 g/mol.

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.
