Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2175-90-8 I8CJ7P33G3 6,6'-Diphenylfulvene Benzene, (2,4-cyclopentadien-1-ylidenephenylmethyl)- (9CI) Methane, 2,4-cyclopentadien-1-ylidenediphenyl- (8CI) Benzene, 1,1'-(2,4-cyclopentadien-1-ylidenemethylene)bis- Diphenylfulvene 6,6-Diphenylfulvene 5-(Diphenylmethylene)-1,3-cyclopentadiene EINECS 218-533-4 NSC 402188 UNII-I8CJ7P33G3.

2175-90-8 I8CJ7P33G3 6,6'-Diphenylfulvene Benzene, (2,4-cyclopentadien-1-ylidenephenylmethyl)- (9CI) Methane, 2,4-cyclopentadien-1-ylidenediphenyl- (8CI) Benzene, 1,1'-(2,4-cyclopentadien-1-ylidenemethylene)bis- Diphenylfulvene 6,6-Diphenylfulvene 5-(Diphenylmethylene)-1,3-cyclopentadiene EINECS 218-533-4 NSC 402188 UNII-I8CJ7P33G3 (CAS 2175-90-8) is a high-purity analytical reference standard with the molecular formula C18H26 and a molecular weight of 242.40 g/mol.

Based on its molecular formula C18H26, 2175-90-8 I8CJ7P33G3 6,6'-Diphenylfulvene Benzene, (2,4-cyclopentadien-1-ylidenephenylmethyl)- (9CI) Methane, 2,4-cyclopentadien-1-ylidenediphenyl- (8CI) Benzene, 1,1'-(2,4-cyclopentadien-1-ylidenemethylene)bis- Diphenylfulvene 6,6-Diphenylfulvene 5-(Diphenylmethylene)-1,3-cyclopentadiene EINECS 218-533-4 NSC 402188 UNII-I8CJ7P33G3 contains an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 242.40 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), 2175-90-8 I8CJ7P33G3 6,6'-Diphenylfulvene Benzene, (2,4-cyclopentadien-1-ylidenephenylmethyl)- (9CI) Methane, 2,4-cyclopentadien-1-ylidenediphenyl- (8CI) Benzene, 1,1'-(2,4-cyclopentadien-1-ylidenemethylene)bis- Diphenylfulvene 6,6-Diphenylfulvene 5-(Diphenylmethylene)-1,3-cyclopentadiene EINECS 218-533-4 NSC 402188 UNII-I8CJ7P33G3 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.
