Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 698-26-0 5-Chloro-1H-indazole 1H-Indazole, 5-chloro- 5-23-06-00175 (Beilstein Handbook Reference) BRN 0003260 5-Chloroindazole EINECS 211-812-1 NSC 78434.
698-26-0 5-Chloro-1H-indazole 1H-Indazole, 5-chloro- 5-23-06-00175 (Beilstein Handbook Reference) BRN 0003260 5-Chloroindazole EINECS 211-812-1 NSC 78434 (CAS 698-26-0), molecular formula C7H13ClN2 and molecular weight 160.64 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, chlorine substitution, 698-26-0 5-Chloro-1H-indazole 1H-Indazole, 5-chloro- 5-23-06-00175 (Beilstein Handbook Reference) BRN 0003260 5-Chloroindazole EINECS 211-812-1 NSC 78434 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 160.64 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
