Description

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

XQJ55R5PPQ 882531-87-5 R-1530 UNII-XQJ55R5PPQ 5-(2-Chlorophenyl)-7-fluoro-1,2-dihydro-8-methoxy-3-methylpyrazolo(3,4-b)(1,4)benzodiazepine Pyrazolo(3,4-b)(1,4)benzodiazepine, 5-(2-chlorophenyl)-7-fluoro-1,2-dihydro-8-methoxy-3-methyl- (CAS 882531-87-5), molecular formula C18H14ClFN4O and molecular weight 356.78 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/chlorine substitution, XQJ55R5PPQ 882531-87-5 R-1530 UNII-XQJ55R5PPQ 5-(2-Chlorophenyl)-7-fluoro-1,2-dihydro-8-methoxy-3-methylpyrazolo(3,4-b)(1,4)benzodiazepine Pyrazolo(3,4-b)(1,4)benzodiazepine, 5-(2-chlorophenyl)-7-fluoro-1,2-dihydro-8-methoxy-3-methyl- is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 356.78 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).

As a certified reference material (CRM), XQJ55R5PPQ 882531-87-5 R-1530 UNII-XQJ55R5PPQ 5-(2-Chlorophenyl)-7-fluoro-1,2-dihydro-8-methoxy-3-methylpyrazolo(3,4-b)(1,4)benzodiazepine Pyrazolo(3,4-b)(1,4)benzodiazepine, 5-(2-chlorophenyl)-7-fluoro-1,2-dihydro-8-methoxy-3-methyl- meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
