It is extensively utilized as a biological stain in microscopy, particularly for visualizing acid-fast bacteria (AFB) in Ziehl-Neelsen and Gram staining protocols. Additionally, it serves as a highly effective colorant in the textile, leather, and cosmetics industries, where it yields a dark red to light purple hue in solution.<\/p>\n<h3>Specification<\/h3>\n<table>\n<tbody>\n<tr>\n<td width=\"50%\">Item<\/td>\n<td width=\"50%\">Value<\/td>\n<\/tr>\n<tr>\n<td width=\"50%\">Appearance<\/td>\n<td width=\"50%\">Dark green crystals or crystalline powder<\/td>\n<\/tr>\n<tr>\n<td width=\"50%\">Boiling Point<\/td>\n<td width=\"50%\">300 \u2103 [at 101 325 Pa]<\/td>\n<\/tr>\n<tr>\n<td width=\"50%\">Density<\/td>\n<td width=\"50%\">0.692 [at 20 \u2103]<\/td>\n<\/tr>\n<tr>\n<td width=\"50%\">Storage Conditions<\/td>\n<td width=\"50%\">Store at +5 \u00b0C to +30 \u00b0C<\/td>\n<\/tr>\n<tr>\n<td width=\"50%\">Water Solubility<\/td>\n<td width=\"50%\">20 g\/L<\/td>\n<\/tr>\n<tr>\n<td width=\"50%\">pH<\/td>\n<td width=\"50%\">3-4 (10g\/l, H2O, 20 \u2103)<\/td>\n<\/tr>\n<tr>\n<td width=\"50%\">Stability<\/td>\n<td width=\"50%\">Stable.
