Hematoxylin is a dye for the specific staining of DNA in the nuclei. It is used in cytology and histology. Nuclei are stained blue, dark violet to black. Hematoxylins are mixed with trivalent positively charged metal salts and build up the so-called hematoxylin lakes, used for the selective staining of nuclei (DNA). Certistain is the product group for seleceted high quality dyes that fulfill all quality requirements for IVD.||Synonyms:|Natural black 1; CI 75290; (6aS,11bR)-7,11b-Dihydrobenz[b]indeno[1,2-d]pyran-3,4,6a,9,10(6H)-pentol; (+)-Hematoxylin; Haematoxylin; Hematoxylin; Hematoxyline; Hydroxybrasilin; Hydroxybrazilin; NSC 270085; (6aS-cis)-7,11b-Dihydro-benz[b]indeno[1,2-d]pyran-3,4,6a,9,10(6H)-pentol; (6aS, 11bR) -7, 11b- Dihydro- benz[b] indeno[1, 2- d] pyran- 3, 4, 6a, 9, 10(6H) pentol||CAS No:|517-28-2||Molecular Formula:|C16H14O6||Molecular Weight:|302.29||Appearance:|Fine, Beige to tan to light brown powder ||Dye Content:|≥80%||Visual Transition Interval:|5.0-7.2, yellow to violet||Melting Point:|>200°C (dec.)||Solubility:|Alcohol: To pass test||Water (KF):|≤8%||UV Ratios:|Peak 524 ± 2nm, ratio 1 ± 0.5 at 509/539nm Density at peak 0.474 ± 0.5au||Storage and Stability:|May be stored at RT.
