(S)-2-fluoro-7-(1-methoxy-2-methylpropyl)pyrazolo[1,5-a]pyrimidine-6-carboxylic acid CAS 2097854-07-2

Description

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.

(S)-2-fluoro-7-(1-methoxy-2-methylpropyl)pyrazolo[1,5-a]pyrimidine-6-carboxylic acid (CAS 2097854-07-2), molecular formula C12H14FN3O3 and molecular weight 267.26 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, (S)-2-fluoro-7-(1-methoxy-2-methylpropyl)pyrazolo[1,5-a]pyrimidine-6-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 267.26 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).

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.
