6-chloro-4-(methylsulfanyl)-1H-pyrazolo[3,4-d]pyrimidine CAS 6288-85-3

Description

The occurrence of 6-chloro-4-(methylsulfanyl)-1H-pyrazolo[3,4-d]pyrimidine is closely related to an amide group, a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

6-chloro-4-(methylsulfanyl)-1H-pyrazolo[3,4-d]pyrimidine (CAS 6288-85-3) is a high-purity analytical reference standard with the molecular formula C11H18NO4PS and a molecular weight of 291.30 g/mol.

6-chloro-4-(methylsulfanyl)-1H-pyrazolo[3,4-d]pyrimidine (C11H18NO4PS) contains an amide group, a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

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.
