6-Amino-3-tert-butyl-4-(2,6-difluorophenyl)-2H,4H-pyrano[2,3-c]pyrazole-5-carbonitrile CAS 371222-98-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Amino-3-tert-butyl-4-(2,6-difluorophenyl)-2H,4H-pyrano[2,3-c]pyrazole-5-carbonitrile.

6-Amino-3-tert-butyl-4-(2,6-difluorophenyl)-2H,4H-pyrano[2,3-c]pyrazole-5-carbonitrile (CAS 371222-98-9), molecular formula C17H16F2N4O and molecular weight 330.33 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 6-Amino-3-tert-butyl-4-(2,6-difluorophenyl)-2H,4H-pyrano[2,3-c]pyrazole-5-carbonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 330.33 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.
