Hematoxylin Chemical Properties,Uses,Production
Chemical Properties
light brown crystals or powder
Uses
Hematoxylin and eosin together make up Hematoxylin and eosin stain, one of the most commonly used stains in histology. Metal-haematein complexes are used to stain cell nuclei prior to examination under a microscope. Structures that stain with iron- or aluminum-haematein are often called basophilic, even though the mechanism of the staining is different from that of staining with basic dyes.
Uses
Colorant in inks, biological stains.
Definition
ChEBI: (+)-haematoxylin is a haematoxylin. It is an enantiomer of a (-)-haematoxylin.
General Description
White to yellowish crystals that redden on exposure to light.
Air & Water Reactions
Soluble in hot water, slightly water soluble in cold .
Reactivity Profile
Sensitive to light. .
Hazard
May be carcinogenic.
storage
Store at RT
Purification Methods
Hematoxylin recrystallises from H2O (as trihydrate) in white-yellow crystals which become red on exposure to light and then melt at 100-120o. It has been recrystallised from Me2CO/*C6H6. It has been recrystallised as well from dilute aqueous NaHSO3 until colourless and is soluble in alkali, borax and glycerol. Store it in the dark below 0o.
