Bis(ethylbenzene)chromium [mixture of (C2H5)xC6H6-x where x = 0-4)] CAS 12212-68-9

Description

The occurrence of Bis(ethylbenzene)chromium [mixture of (C2H5)xC6H6-x where x = 0-4)] is closely related to an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Bis(ethylbenzene)chromium [mixture of (C2H5)xC6H6-x where x = 0-4)] (CAS 12212-68-9), a certified reference material (molecular formula C8H10Cr, MW 158.16 g/mol) for analytical method development and quality control.

Owing to an aromatic ring system, Bis(ethylbenzene)chromium [mixture of (C2H5)xC6H6-x where x = 0-4)] is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 158.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
