6-Chloro-4-ethoxy-1H-pyrazolo[3,4-d]pyrimidine CAS 99980-45-7

Description

The occurrence of 6-Chloro-4-ethoxy-1H-pyrazolo[3,4-d]pyrimidine is closely related to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

6-Chloro-4-ethoxy-1H-pyrazolo[3,4-d]pyrimidine (CAS 99980-45-7), molecular formula C7H7ClN4O and molecular weight 198.61 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 6-Chloro-4-ethoxy-1H-pyrazolo[3,4-d]pyrimidine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 198.61 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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