Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Benzyl 3-bromo-2-formyl-6,7-dihydropyrazolo[1,5-a]pyrazine-5(4H)-carboxylate.
Benzyl 3-bromo-2-formyl-6,7-dihydropyrazolo[1,5-a]pyrazine-5(4H)-carboxylate (CAS 2836310-01-9), molecular formula C15H14BrN3O3 and molecular weight 364.19 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, bromine substitution, Benzyl 3-bromo-2-formyl-6,7-dihydropyrazolo[1,5-a]pyrazine-5(4H)-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 364.19 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.
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.
CATO manufactures Benzyl 3-bromo-2-formyl-6,7-dihydropyrazolo[1,5-a]pyrazine-5(4H)-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
