Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 34822-90-7 Cyclopentadienylthallium Thallium, pi-cyclopentadienyl- (8CI) Thallium, (eta5-2,4-cyclopentadien-1-yl)- (9CI) Thallium, (eta5-2,4-cyclopentadien-1-yl)- EINECS 252-229-2 NSC 114719 Thallium cyclopentadienide Thallous cyclopentadienide.
CATO supplies 34822-90-7 Cyclopentadienylthallium Thallium, pi-cyclopentadienyl- (8CI) Thallium, (eta5-2,4-cyclopentadien-1-yl)- (9CI) Thallium, (eta5-2,4-cyclopentadien-1-yl)- EINECS 252-229-2 NSC 114719 Thallium cyclopentadienide Thallous cyclopentadienide (CAS 34822-90-7), a certified reference material (molecular formula TlC5H5, MW 269.47 g/mol) for analytical method development and quality control.
Owing to an organic framework, 34822-90-7 Cyclopentadienylthallium Thallium, pi-cyclopentadienyl- (8CI) Thallium, (eta5-2,4-cyclopentadien-1-yl)- (9CI) Thallium, (eta5-2,4-cyclopentadien-1-yl)- EINECS 252-229-2 NSC 114719 Thallium cyclopentadienide Thallous cyclopentadienide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 269.47 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).
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.
